In the late 90s, Lucent increased its growth by lending money to the telecom startups buying its equipment. Revenue looked incredible up until the customers couldn't pay and Lucent was left holding both the bad loans and the collapse in demand.

Nvidia is now backing ~$105B in financing for OpenAI's Ohio data center, on top of the $30B it already put into OpenAI directly.

The difference this time, maybe, is that AI demand is real in a way that a lot of dot-com telecom demand wasn't.

Is this durable demand that justifies the financing or a delayed growth loop that works until it doesn't? I hold the stock and I still can't decide.

HBM is the expensive fast memory that's in short supply and driving the whole AI hardware trade right now. Last week SK Hynix and SanDisk dropped a standard for a new thing called High Bandwidth Flash that basically slots in underneath it, almost as fast but with way more capacity for cheaper. Google's already on board.

It's built for AI inference, not training. training is the one-time cost of building the model; inference is every time someone actually uses it, which is forever. It feels like the whole industry is shifting from pay once to build it to pay forever to run it, and the memory everyone's crowded into might be the wrong one for where this is actually going.

Please tell me I'm not overthinking this one.

The Rubin Ultra reporting this week is that NVIDIA's testing configs with as little as 192GB of HBM, down from a planned 1TB, and even stepping back from HBM4E to HBM4. Not for performance, purely because the memory shortage is bad enough that it's limiting how many racks get built. Nothing's final but multiple firms are describing the same thing.

The part that matters imo for holding AI names: what NVIDIA gives up in memory it reportedly takes back in optics, more photonic interconnect instead of more memory stacked next to the chip. So the value doesn't disappear, it moves to a different part of the supply chain. And you could see the market chewing on that through early August, memory names under pressure while photonics and co-packaged-optics names caught a bid.

What's been on my mind is what this does to the "just own AI" thesis. For most of this year you could own the broad AI trade, memory especially, and ride it up. But if the whole chain is short at once, lasers reportedly sold out years deep, TSMC apparently sitting on finished chips it can't package for lack of memory, then OEMs keep making forced trade-offs, and each one shifts money between verticals on a timeline that has nothing to do with actual end demand.

Any clean answer for how you position around that?

Picking the right layer suddenly matters way more than it did six months ago, but the winning layer keeps changing based on whatever's scarcest that quarter.

Disclosure up front: I work on a project this is based on, an open source browser MMO. Not linking it since this is about the tools, not the game.

We got an unusual comparison for free. The original build was generated by Claude Fable 5, which was pulled worldwide three days after we shipped, so we were forced to migrate everything onto other models rather than choosing to. Since then it's run on Opus and GPT-5.5.

What actually differed:

Music generation was the widest gap by far. Fable wrote soundtrack code programmatically in TypeScript in a way nothing else came close to replicating. We ended up hiring a human composer instead.

Environment generation degraded noticeably. Same prompting effort, worse output, more iteration to reach the same place.

Everything else was close to interchangeable. Game systems, combat logic, quest content, debugging, refactors. GPT-5.5 handled the systems work well enough that the migration was mostly invisible in the shipped product.

The takeaway I didn't expect: the differences that show up in benchmarks aren't the ones that hurt when you switch. The narrow creative capabilities were the fragile part, and the bulk engineering work was portable.

Can share more if you're interested. :)

Fable 5 launched in June and was withdrawn worldwide days later under a US export directive. It came back later, but the gap is the interesting part, because anyone who'd built on it in that window found out what happens when the capability underneath your product disappears on someone else's decision.

I've seen this play out on a gaming project I work on. What surprised me was which parts survived. Narrow creative capabilities were the fragile ones, music generation specifically was effectively model-exclusive and just left. The bulk engineering work moved to other models with barely any friction.

The trend worth watching: most discussion of model risk is about vendors deprecating things or changing prices. Export controls are a different category, because the decision isn't the vendor's and there's no negotiating with it. If you're outside the US and building on frontier models, your access is subject to policy you have no visibility into.

Recently read investors apparently sold 20 times the two year average weekly flow of memory and semiconductor stocks in late July, third weekly sale in four weeks after 10+ weeks of buying. All after retailed purchased 23 times the average in June. Talk about a full sentiment reversal.

However, physical market seems to be going the othe way. DRAM and HBM pricing is up sharply, mainly because memory makers are reallocating fab capacity towards AI-grade products. Retail is pointing left and fab economics is pointing right. Any ideas of what could be happening?

This question has been on my mind for a while, mainly because someone personally close to me is experiencing it currently, and every time I feel like I've come up with something solid another scenario inverts that feeling.

The most convincing case for legalizing it is not even about terminal illness. It's about the arbiters of who decides if another's suffering qualifies as sufficient. Even the most compelling reason against doing so is not about discomfort. You know how quickly "you get to choose" becomes (as soon as cost/care burden/family pressure come into play) "you're expected to choose".

Where I keep ending up: I'd be in favor of it, if there were security features no one has seemed to sign on to. Independent psychiatry consultation from the treating doctor A waiting period sufficient to differentiate a curable episode of depression from an ostensibly firm decision. No willingness to cover anywhere near the choice or cost.

Convince me what should be on either side of that line, or tell me what would persuade you to flip from a no vote into the yes camp.

Rising More than Threefold to $33.5B, institutions Like BlackRock and the DTCC Push Forward.

Despite that fact, these are not significant numbers: 56% of large tokenized assets have zero weekly transfers and only ~10% are deployed to DeFi.

This divergence between market cap growth and real world usage begs the question, is this actual adoption or just sleepy custody as an initial phase until onchain use eventually scales?

Keep seeing more platforms offering tokenized US equities, buy and hold real company exposure with crypto, no broker, trade 24/7. Sounds great on paper but curious how it actually holds up for people trading real size rather than just testing it out.

Some questions I always think of, how's the spread when you're actually trying to size in or out of a position, not just holding long term? Has redemption ever been slow or messy for anyone, or has it been smooth? Does the 24/7 trading actually matter in practice, or does liquidity just dry up outside normal market hours anyway?

Genuinely trying to figure out if this is a real trading tool yet or still mostly a buy-and-hold novelty.

It seems like every quarter or so, someone has a pitch for why crypto is going to allow this magical equal access into the marketplace where you have no brokerage account, you're free of wire transfer requirements and we can all ignore banking hours.

Wondering how much of that is real in practice vs aspirational.

If you are outside the US and have actually tried to gain exposure via some form of tokenized or onchain route, how did that go for ya?

Real liquidity, reasonable spread, redemption working as intended or falling apart at the moment of trying to get back money?

Keep seeing threads about buying tokenized versions of US stocks with stablecoins, no broker, no wire transfer, trade 24/7. Sounds great in theory but I want to hear from people who've actually used one of these, not just read the marketing.

Some questions I like to think about:

How's liquidity when you actually try to get out, not just in? Anyone hit a redemption that didn't go the way they expected? And is the spread actually tight enough to matter compared to just eating a normal broker's fees?

Not shilling anything specific, genuinely trying to figure out if this category is real yet or still mostly hype with a few working products buried in a pile of nothing.

No ads, no paywall, nothing locked behind payment. The whole codebase is MIT licensed and public on GitHub, so you can also self-host your own server if you want.

It's still rough in places, performance can be spotty depending on your browser, and it's clearly a smaller project than the games it's imitating. But it's genuinely free and there's a community actively adding to it, someone recently built a whole Fall Guys style party mode into it.

They're based in Wellington. A few months back they built something called World of ClaudeCraft, a classic-style MMO you play straight in the browser, nothing to install.

It's got nine classes, three zones to level through, dungeons, a PvP arena, trading, the normal MMO stuff. Nothing groundbreaking on paper.

What actually surprised me is what happened after they put the code up publicly. People who'd never shipped a game mode in their life started building things on top of it, a Fall Guys style party game, a football minigame, a whole ranked PvP arena, none of that was ours. They went from three people working on it to about thirty, and most of them just found the repo on their own.

It's still small and a bit rough around the edges honestly, but it's free, it's playable right now, and the whole codebase is public if you want to see how it's put together or add something yourself.
