Made a deep dive on the bank that cut 45 call-centre jobs for an AI bot, then asked those people back six weeks later

Commonwealth Bank of Australia cut 45 call-centre roles in July 2025 and named an AI voice bot as the reason. Six weeks later they asked those people back, and put in writing that the decision was an error.

My video walks through why that happens, and it comes down to the containment rate. The bot closes the easy calls, so what reaches a human is the residue: longer, angrier, with no easy calls left to balance out a shift. The callers it can't finish just ring back, so one failed contact turns into two. Containment measures the bot. It doesn't measure the work.

That's the sort of thing I put out on my channel, Dave Saunders. Mostly operator-level breakdowns of where AI actually lands inside a business, from about 30 years of building products.

I spend the first third of each video being fair to the thing I'm about to take apart. Is that costing me viewers?

Small channel, long-form analysis for founders and operators. The format is taking a claim everybody repeats and checking whether it survives contact with the source.

The latest one is the statistic that AI beats lawyers at contract review, 94% to 85%. It traces back to a 2018 vendor whitepaper: five NDAs, twenty lawyers, and the report itself says the answer key was assembled from the best answers of all the participants, the vendor's own AI included. So the system under test helped write the key it was graded against.

My structural problem is everything that comes before that. I spend the first several minutes being scrupulously fair: nobody hid anything, the caveats sit right there in the original document, and it took eight years of repetition to strip them out. I'm convinced that fairness is the only reason the criticism lands at all. I'm also fairly sure it's where I lose the people who clicked expecting a takedown.

So the question for anyone else making analysis or commentary: do you front-load the payoff and backfill the fairness afterward, or earn it in order like I'm doing? I've watched channels do both and I honestly can't tell whether the front-loaders are winning on structure or just winning because they're bigger and the algorithm forgives them more.

AI gets the first 60% of almost anything. Most of the difference is in how you ask.

I made a video about the asking part, because that's where the gap actually lives. Three moves, and none of them are prompt tricks: say what done looks like before you start, feed it the context it can't see, then take the 60% and drive the rest yourself.

The receipt I use is one of my own. A deck into an 11-page MRD at roughly 80% complete, in under 30 minutes of real work. The trap shows up right after a win like that, which is why the video doesn't stop there. The early success is exactly when you drop your guard, and METR's trial found experienced developers 19% slower on their own mature code while feeling 20% faster.

Long-form deep dive on my YouTube channel, aimed at founders and operators rather than at people collecting prompts.

BCG's own study found consultants 40% better with AI, and 19 points worse on the task sitting just outside the frontier

That second number is the one I built a video around. BCG ran the study, and they disclosed their own conflict, which I say plainly on the mic. Inside the frontier of what the model handles well, the consultants got roughly 40% better. On a task deliberately rigged to sit just outside it, the same people came in 19 points worse than the control group.

Here's the thing about that boundary: it is invisible from the inside, and the model sounds equally confident on both sides of it by design. You get the 60% that's right and the 40% that isn't, and the 60% only helps if you already know the subject well enough to catch the 40%. Then comes the part that actually costs people money, which is that you stop checking. Deloitte issued a refund over it. A lawyer filed cases that did not exist.

I make long-form deep dives on my channel, mostly for founders and operators. This one closes on a three-question test for telling solid ground from the ragged edge.

I put both AI coding studies in one video: the 55.8% speed-up and the 19% slowdown are both real

The number everybody quotes is the 55.8% greenfield speed-up. The one nobody quotes is METR's randomized trial, where experienced developers working on their own mature repos finished 19% slower with AI, and walked out of it believing they had been 20% faster.

Both results are real, and reconciling them is the whole video. I spent 30 years shipping product before I started making these, so what I wanted to build was the mechanism underneath: token prediction, the context window, the agentic loop, and who still owns the architecture at the end. Then an honest survey of the three tool tiers, and the Stack Overflow numbers that explain the mood (84% using, 29% trusting, 66% worn down by answers that are almost right).

It's a long-form deep dive on my YouTube channel, slow and mechanism-first, not a tips video. If you're deciding how much of your own workflow to hand over, measure your own drift instead of trusting the feeling.

Next vacuum

I've been a happy Roomba customer for a pretty long time now. I have two of the very first models and I also have a J9+.

I'm contemplating what my next vacuum will be. I have two Samoyeds so my big factor is there's just a lot of little tiny hairs everywhere. What's the robot vacuum that is the pet hair master? I don't really care about the mopping function because my wife has a Bissell upright thingy and likes to use it. So really it's about auto empty vacuuming with intelligent object avoidance.

I run a small channel and finally made the AI tools video I actually wanted to watch: my five real workflows and where each one breaks

Most AI tool videos I watch are demos that stop right before the part I care about, which is where the thing falls over. So I made the other version: the five workflows I actually run every week, and the exact point each one breaks.

I've been doing product development for about 30 years, and the pattern here is familiar. Most of what gets sold as AI right now is machine learning with better marketing on it. The FDA's cleared device list has well over a thousand products running machine learning, and the category quietly got renamed along the way.

My channel started at zero not long ago and the first subscribers came from DMs, so I'm not going to stand here and hand out growth advice. This is just the honest version of a tools video, because the other kind is everywhere already.

The AI running your day isn't the smart one everyone's arguing about

I've spent about 30 years building products, and the AI that changed how I work isn't the chatbot everyone likes to demo. It's the quiet stuff already deciding what I see and what I never get shown. I put together a video on why "is it smart enough" is the wrong thing to argue about, because the systems steering your day don't need much smarts to run it. If you're growing a channel, the same kind of system decides who your work reaches. It's on my channel here: https://youtu.be/lQh1GTl1bWs. I'll be in the comments if you want to get into it.

Was it ever really AI behind those layoffs? Looking at the cuts nobody wants to explain

When the layoffs came, AI got the blame almost every time. Look closer at the numbers and the timing though, and the story stops being so clean. In this video I walk through the cuts nobody really wants to explain and ask whether AI was ever the actual driver. My background is roughly 30 years building products, so I care more about what the evidence shows than what makes a tidy headline. Watch it here: https://youtu.be/CwzkC6q5CXc

Companies blamed AI for the layoffs, then quietly started hiring the same roles back

A lot of companies pinned their layoffs on AI making certain roles unnecessary. Then some of them quietly started hiring for the same positions again. In this one I look at what that pattern actually says about how much of the AI story held up versus how much was a convenient reason. I have spent around 30 years in product development, so I tried to separate the signal from the press release. Here is the full breakdown on my channel: https://youtu.be/QQoxtORMivU

Delegating got easier for me once I stopped treating it as a task problem and fixed the trust underneath

The usual advice is to delegate better by writing clearer instructions. That never fixed it for me. What was actually blocking me was that I did not trust the work would be right unless I did it myself. In this video I dig into where that trust comes from and how to build it so handing things off stops feeling like a gamble. It comes from about three decades of building products and learning this the slow way. Full breakdown here: https://youtu.be/N30Da67yR0U
