Am I solving a real problem

I've been thinking about a different approach to social networking and I'd like honest feedback.

Instead of optimizing for engagement and endless scrolling, what if a platform optimized for helping people achieve their goals?

The core idea is simple:

- You tell the platform what you're trying to accomplish.

- AI helps identify relevant people, opportunities, and information.

- The focus is on meaningful connections rather than maximizing screen time.

I'm not looking to promote anything. I'm trying to understand whether this solves a real problem or whether I'm missing something important.

If this existed, would you use it?

If not, what's the biggest reason you wouldn't?

IsItBullshit: Is there any real danger of the FCC doing anything to ban depiction of LGBTQ+ characters on television?

Saw some post going viral on Tumblr about some sort of potential future regulation to that effect and a comment period that ended yesterday that it was trying to encourage people to comment during. Now I want to know if representation is truly in enough danger to justify the hyperbole of that post talking about how certain characters like [insert a bunch of examples of queer TV characters that they inserted pictures of] could disappear (or to make me afraid to do anything from even ship any non-canon gay ships from currently-airing shows or make an effort to save Brilliant Minds and its gay representation because what's the point if it all could go away) or is that just another instance of something being threatened that's still bad and Tumblr blows it way out of fucking proportion in the name of rallying the masses like when some viral post thought (or at least its poster did yada yada) that the removal of net neutrality would mean every Tumblr user would have to pay 75 cents per post every time they posted?

TV show idea: A political drama about what it would realistically take for the U.S. to peacefully convince Canada to join as a state.

Not through war, threats, or economic coercion. Instead, the entire show is about compromise.

Each season would focus on the negotiations between the two democracies as they try to answer questions like:

  • Would Canada get one state or multiple states?
  • How would representation in Congress work?
  • Could Canada's public healthcare system be preserved?
  • What would happen to Quebec and French language rights?
  • How would Indigenous treaties be handled?
  • What happens to Canada's constitutional monarchy?
  • What tax and social policy compromises would each side have to make?

The premise isn't that annexation is inevitable or even likely. In fact, the show would emphasize just how difficult it would be. Every major issue would require creative solutions that satisfy enough people on both sides.

The interesting question isn't "Could the U.S. take Canada?" It's "Is there any package of compromises that two democratic countries would freely agree to?"

The ending wouldn't even have to be predetermined. The negotiations could ultimately succeed or fail depending on where the story naturally leads.

I don't think I've seen a political drama built around large-scale constitutional negotiation instead of war, elections, or espionage.

Restaurant idea: Set your budget before ordering, and automatically reward the waiter for staying within it.

Imagine a restaurant where the person paying privately specifies a budget before ordering, either when making the reservation or through an app or QR code at the table.

The waiter would then recommend dishes and combinations that provide the best dining experience while staying within that budget. Instead of encouraging customers to spend as much as possible, the waiter is incentivized to help them get the most value within their spending limit.

Part of the tip could be calculated automatically based on how well the waiter stayed within the customer's budget. The closer the final bill is to the target without exceeding it, the larger the budget-matching bonus (up to a limit). The rest of the tip would still be based on the quality of the service.

To avoid awkwardness, the budget would never be mentioned at the table. The recommendations would simply feel well suited to the group.

The menus could even be personalized based on the budget. Rather than removing expensive items, they could subtly highlight dishes and combinations that fit the target price range, making the recommendations feel natural and avoiding any embarrassment for the person paying.

The result would be a restaurant experience where customers feel the staff are working to maximize satisfaction within their budget, rather than simply trying to maximize the bill.

Idea: What if NYC had an annual "Japanese Politeness Week"?

Imagine New York City holding an annual "Japanese Politeness Week."

Every year, for one week, anyone who wants to participate, regardless of nationality, tries to follow Japanese-style etiquette as much as reasonably possible. People speak more quietly, queue neatly, avoid unnecessary noise, give way to others, and generally try to avoid inconveniencing people around them.

The city itself would feel completely different. Rush hour without honking. Crowded subways that are surprisingly quiet. Sidewalks where people are constantly trying to let each other pass first.

To make it more interesting, participants could opt into a lottery with a large cash prize at the end of the week. However, if they are caught clearly violating the etiquette guidelines during the week, they become ineligible. The point isn't punishment, but to create a fun incentive for people to genuinely try.

Over time, it could become one of NYC's signature annual events, attracting tourists who want to experience a version of the city that feels completely different from the other 51 weeks of the year.

I'm not necessarily suggesting this should actually happen. I'm mostly curious what would happen socially. Would people look forward to it every year? Would some habits gradually stick beyond the event? Would the city feel noticeably less stressful during that week? Or would everyone be counting down until they could go back to normal?

It seems like an interesting way to explore how much of a city's atmosphere comes from shared social norms, and how quickly those norms can change when enough people consciously participate.

Idea: Could suppressing physical attraction make dating fairer by shifting the focus to personality and compatibility?

A lot of dating involves being judged on traits that people have little or no control over, such as race, beauty, and height. We generally accept this because physical attraction is considered an unavoidable part of human nature.

But what if, in the future, there were a safe medication that could significantly reduce physical attraction while preserving emotional attachment, companionship, and the ability to have fulfilling relationships?

Would dating become fairer if people chose partners primarily based on personality, values, intelligence, humor, and long-term compatibility instead of physical appearance?

I'm not suggesting everyone should take such a medication. I'm questioning whether physical attraction should always be treated as something beyond criticism simply because it's natural. Many natural human tendencies, such as certain cognitive biases, can produce unfair outcomes, and we often look for ways to mitigate them.

Would reducing the influence of physical attraction create healthier and more equitable relationships, or would it remove something essential from what makes romantic love different from friendship?

Idea: What if living alone became illegal for mental health reasons, but the required roommate was an intelligent human-like robot?

Many studies link long term social isolation with poor mental and physical health. As AI and robotics improve, imagine a future where everyone who lives alone is required to have an intelligent human-like robot as a roommate.

The robot wouldn't just be a voice assistant. It would be a physically present companion that could hold conversations, notice changes in mood, encourage healthy habits, remind you to stay in touch with friends and family, and call for help in an emergency.

Society already accepts some laws that limit personal freedom to improve public health. If living alone were eventually shown to have severe long term health consequences, could requiring an AI robot companion be justified in the same way?

Would this be an unacceptable violation of personal freedom, or could it eventually become as normal as requiring smoke detectors in homes?

Idea: A city where same race marriage is illegal, while the rest of the country has no such restriction.

Living in the city would be entirely optional. Anyone who preferred the usual marriage laws could simply live elsewhere.

The idea isn't to punish anyone. The goal would be to see whether a voluntary city with this single unusual rule would become less racially divided over time. After a few generations, would there be fewer racial boundaries, less prejudice, and a stronger shared identity? Or would the policy create more problems than it solves?

Do you think such a city would become less racist than comparable cities, or would the costs of restricting marriage outweigh any potential long-term benefits?

Would you actually use an AI assistant built into a mirror? Looking for honest feedback.

I’ve been thinking about a product idea and I’m trying to figure out if it solves a real problem or if it’s just a cool futuristic concept.
The idea: a mirror that acts like a personal AI assistant. You wake up, say “good morning,” and it gives you a personalised briefing, your calendar, weather, reminders, important tasks, and anything you need to know for the day. You could also ask it questions like you would with Siri or ChatGPT.
The goal wouldn’t just be a “smart mirror,” but more like having an AI assistant that becomes part of your daily routine.
A few questions:
Would you actually use something like this every morning?
What features would make it genuinely useful?
What would make you not want one?
Would you pay for something like this? If yes, what price range feels reasonable?
I’m not selling anything. I’m just trying to understand whether this is a useful idea or just a fun concept.
Appreciate any honest opinions.

Idea: What if elementary school reunions hired a professional actor or actress to play your kindergarten or grades 1 to 3 teacher?

Everyone knows it's an actor. But they look, dress, talk, and behave just like your teacher did, using the same catchphrases and classroom routines throughout the reunion.

Imagine being in your 50s and hearing, "Eyes on me!" or "No talking while I'm talking!" and instinctively sitting up straighter.

It would be like stepping back into elementary school for one evening, except everyone has gray hair.

Idea: A lottery where the less you pay for a ticket, the more of your winnings go to charity.

Suppose the maximum ticket price is $10, but you can choose to pay any amount up to that.

If you win, the percentage of the maximum ticket price that you paid is the percentage of the prize that you keep. The rest is automatically donated to charity.

For example:

  • Pay $10 → Keep 100% of the prize.
  • Pay $7 → Keep 70%, and 30% goes to charity.
  • Pay $3 → Keep 30%, and 70% goes to charity.

Everyone has the same odds of winning regardless of how much they pay. The only difference is how any prize is divided between the winner and charity.

This lets players decide in advance how much of a potential prize they are willing to donate, while still giving everyone the same chance of winning.

Idea: A front yard that begs passersby for water to motivate the homeowner to water it before it's embarrassing.

What if front yards could politely ask passersby for water when they actually need it?

Imagine a front yard with soil moisture sensors connected to a speaker. When the soil gets too dry, it might say something like:

>"I'm thirsty! Could someone remind my owner to water me?"

The idea isn't really to get pedestrians to water the lawn. It's to give homeowners a way to motivate themselves. If you know your yard will publicly announce that it's been neglected, you're more likely to water it before that happens. It's basically a form of self-imposed accountability, similar to telling friends about a goal so you're more likely to follow through.

The messages could be humorous instead of annoying, and they'd only activate when the soil moisture actually falls below a healthy level.

Would you install something like this, or would it be too embarrassing?

Idea: What if we treated the dead more like we treat the living?

We would never bury a living person or set a living person on fire. Those are some of the worst things we can imagine doing to someone. Yet after death, burial and cremation are considered normal and respectful.

What if our default approach were instead to treat the dead as similarly to the living as practical? For example, imagine a protected island or other isolated place where bodies are simply laid to rest and left undisturbed. Nature would eventually take its course, but the point wouldn't be to "return the body to nature." The point would be that no one is actively burying or burning the body.

I know this isn't a logical argument in the sense that a dead person no longer experiences anything. It's more about the psychology. Many people imagine what it would feel like to have their body buried or cremated, even though they wouldn't actually experience it. I wonder if treating the dead in a way that more closely resembles how we treat the living would make death feel less frightening to some people.

Daylight saving time without the overnight shock: 10 minutes per day for six days

Most debates about daylight saving time are framed as only two options:

  1. Keep the current system
  2. Abolish seasonal time changes completely

But maybe there is a third option.

The biggest problem may not be summer time itself, but the sudden one-hour jump in spring.

Instead of moving clocks forward by one hour overnight, a country could move gradually into summer time: 10 minutes per day for six days.

Same final result. No sudden one-hour shock.

Nobody would have to adjust clocks manually every day. Phones, computers, calendars, transport systems and other digital services already handle time-zone rules automatically. This would simply be a different transition rule.

With countries that still use the traditional one-hour jump, coordination differences would last only five days per year. From day six onward, everything would be aligned again until the next spring.

The autumn transition could remain unchanged, since gaining one hour is much easier for most people.

So the idea is not necessarily to make DST permanent or abolish it, but to make the spring transition softer. We could keep the benefits of DST without the abrupt transition shock.

Would you support this as a third option in the DST debate?

troughs texturized onto the inner surface of fridge/AC/HP tubes heighten energy efficiency 8-12%

Hi, I read there was lots of recent appreciation of cooling technologies. utilizing refrigerant superwettability shapes at fridge tubes Is nonsentient AI grok estimated at saving 8%-12% of the energy used at dwelling AC, refrigerators, and other cooling technologies.

I appreciate and respond to comments.

I read about water and dirt shedding/resistant microcolumnular surfaces, the opposite of that, a 3D angled trough shape  \_/\_/ \_/\_/ \_/\_/ is published as heightening wettability. I thought that if the volume of refrigerator tubes have a microtrough pattern, wettability and refrigerant fluid greater amount of being at the tube surface could occur. I prompted nonsentient AI which communicated this is likely to function and be 8-12% greater energy efficient

Grok nonsentient AI prompt: would minute concave troughs at the refrigerant side of the refrigerant path tube of a refrigerator heighten energy efficiency from greater amount of favored refrigerant and tube wetting, estimate %

response:

**Yes, minute concave troughs (micro-grooves, longitudinal or herringbone channels, or textured surfaces) on the inner refrigerant-side wall of tubes (especially in evaporators) can meaningfully improve energy efficiency.** This is a known enhancement technique in heat exchanger design, often called **microfin or enhanced tubing**. Here's a technical breakdown as if we're optimizing a system together.

### How It Works (Mechanisms)

  1. **Increased Surface Area & Wetting**:
       - Concave troughs create capillary action that pulls liquid refrigerant into the grooves, promoting **thin-film evaporation** across more surface area instead of slug/plug flow.
       - Better **tube wetting** reduces dry-out zones (where vapor blankets the wall, hurting heat transfer). This is especially useful in horizontal tubes or low-flow conditions common in household/commercial refrigerators.

  2. **Favored Refrigerant Amount / Retention**:
       - Grooves increase the effective **wetted perimeter** and hold a thin layer of liquid refrigerant via surface tension. This doesn't drastically increase total charge volume (refrigerant inventory) but improves **distribution and contact time**.
       - In evaporators: Enhances nucleate boiling and convective evaporation coefficients.
       - In condensers: Can aid film condensation by channeling condensate away from the wall.

  3. **Flow & Heat Transfer Benefits**:
       - Turbulence inducement at low Reynolds numbers (typical in fridge tubing) without excessive pressure drop.
       - Reduced thermal resistance at the wall-fluid interface.

### Estimated Efficiency Gains
Real-world data from enhanced tubes (microfin, grooved, or dimpled) in refrigeration/AC systems shows:

- **Heat transfer coefficient (h) improvement**: Typically **50–200%+** in evaporators (depending on geometry, refrigerant—e.g., R600a, R290, R134a/R404A—and flow regime). Modern microfin tubes often achieve 1.5–3x higher h vs. smooth tubes.
- **Overall system energy efficiency (COP or EER)**:
  - **5–15% improvement** in many optimized domestic/commercial refrigerators or heat pumps.
  - In some studies on grooved evaporators: 8–12% reduction in energy consumption for the same cooling capacity, or equivalently higher COP.
  - Upper end (~15–20% in ideal cases) when combined with optimized charge, compressor matching, and minimal added pressure drop.

**Caveats on the Estimate**:
- Gains are **not purely from "greater amount of favored refrigerant"**—total charge might increase slightly (better retention), but the main win is **higher effective heat transfer area and coefficient**, allowing the compressor to run less or at lower pressure ratio.
- **Pressure drop penalty**: Deep/aggressive troughs can increase ΔP (5–20%), hurting efficiency. Optimal designs (shallow concave troughs, e.g., 0.1–0.3 mm depth, helical or axial) balance this—net gain remains positive.
- Real % depends on:
  - Refrigerant (low-GWP naturals like isobutane benefit well).
  - Operating conditions (evaporator temps ~ -20°C to 0°C in fridges).
  - Tube diameter/material (copper/aluminum).
  - System integration (e.g., variable-speed compressors amplify benefits).

Since ~2010s, manufacturers (e.g., in high-efficiency models from LG, Samsung, Whirlpool) have adopted advanced micro-channel or internally enhanced tubes precisely for these reasons, contributing to MEPS (Minimum Energy Performance Standards) compliance. Gains are well-documented in ASHRAE papers and manufacturer teardowns.

**Bottom Line**: Yes—implementing well-designed minute concave troughs (micro-grooves) is a solid efficiency upgrade, likely netting **~8–12%** system-level energy savings in a typical fridge, with potential for more in optimized new designs. Trade-offs include slightly higher manufacturing cost and ensuring oil return (grooves help with this too via capillary action). If prototyping, start with CFD (e.g., ANSYS) on groove geometry and test Δh vs. ΔP. Want specifics on geometry or refrigerant? We can refine the estimate.

I put this as a public domain post at scmp.com Some readers and engineers may have heard of surfaces textured with water avoiding/water excluding microcolumns.  The opposite of that, micro trough shapes, greatly heighten wetting ability (wettability). Nonsentient AI grok says that if the refrigeration/air conditioner refrigerant tubes were microsurfaced with troughs \_/\_/ the cooling/freezing would be 8-12% more efficient. This is a public domain technology any company can utilize.

Users kept choosing the “wrong” feature, so I rebuilt around it

I built an app for people to swipe on topics, match with someone who disagrees, and get scored on civility.

The idea was that if you were constantly an asshole, your civility score would follow you.

But I added a side feature called toxic mode where there was no civility score and people could just argue.

Every user went straight to toxic mode.

That taught me two things.

First, users do not always care about the product you think you built. They care about the part that creates the strongest reaction.

Second, my funnel was way too long for something that needed two people online at the same time. Ad to site to app store to install to onboarding to swiping to matching to finally chatting was just way too much friction.

So I was like ok lets just see if the friction is the issue here

 I made a lightweight browser version focused on the behavior people were already choosing.

No install. No app store. Just pick a topic and jump in.

https://thinklavender.com/ragebait

The bigger lesson for me was to watch what users actually do, especially when it is not what you wanted them to do.

Curious if other founders here have had users prefer the “wrong” feature and whether you followed it or kept pushing your original vision.

Movie idea: A street gang made up entirely of disgruntled geniuses.

Instead of drugs, guns, or robbery, this gang's weapon is intelligence.

The members are all exceptionally high IQ individuals who feel cheated by society. They believe they deserved far more success and respect than they received, and have grown to resent what they see as a world that rewards charisma, luck, and mediocrity over intellect.

Rather than committing conventional crimes, they wage a psychological war against the public.

They leave incredibly difficult puzzles throughout the city, hijack public displays with riddles, and orchestrate elaborate intellectual challenges that bring daily life to a halt. Their goal isn't to kill people. It's to humiliate them. Every unsolved puzzle is, in their eyes, proof that society is intellectually inferior.

Ironically, they develop a devoted online following. Like minded people donate money to support them, believing they're exposing an anti-intellectual culture and forcing people to confront uncomfortable truths.

The drama comes from several directions:

  • The public is divided between those who see the gang as dangerous narcissists and those who see them as misunderstood visionaries.
  • Law enforcement struggles because many of the gang's actions exist in a legal gray area. They're disruptive and intimidating, but often not traditional crimes.
  • Tension grows within the gang itself. Some members simply want recognition, while others become consumed by resentment and push for increasingly extreme acts to prove their superiority.
  • A detective who isn't necessarily the smartest person in the room gradually realizes that understanding people is more important than solving puzzles, turning the conflict into one of emotional intelligence versus raw intellect.

At its core, the movie explores whether intelligence alone entitles someone to success, and how resentment can transform gifted people into extremists.

Idea: Discourage displaying home-country flags on cars during the World Cup in multiracial countries.

In multiracial countries, it would be better to discourage people from displaying the flags of their home countries on their cars during the World Cup.

Most people who do this are simply celebrating their heritage and supporting their team. However, when thousands of vehicles are covered in different national flags, it can also reinforce divisions by emphasizing people's countries of origin rather than their shared national identity.

Instead of banning the practice, governments or community organizations could run frequent public service announcements during the tournament encouraging people to celebrate in ways that bring everyone together. The message could be that supporting your team is great, but doing so without turning public spaces into displays of competing national identities may help promote greater social cohesion in a diverse society.

The idea would be to encourage a stronger sense of unity while still allowing people to enjoy the World Cup and celebrate respectfully.

Show Idea: School that teaches children how to be the henchman of a supervillain

Notice I said "a supervillain" and not "supervillains" in general because this would specifically be the one for a particular very successful supervillain that already has world domination that is training up a force of loyal yet cunning individuals.

They'd probably get into this school in the first place to learn how to be enforcers, probably because that role would be idolized within the supervillain's society.

It would be potentially extremely funny if the main heroes the supervillain is fighting against are also just a group of children, like the actual main protagonists would be.

A premise is nothing without a character who specifically clashes or interacts with it, so perhaps a main character who thinks they can flout rules and still have the highest position standing with the supervillain themselves could cause a bit of humor when they mess things up for other characters, especially if it causes failures relating to the actual heroes.

It would basically be like Evil Con Carne/Villainous mixed with literally countless shows about "child goes to school to learn cool thing to become a hero."
