Slightly overstated. Tiny teams aren't outcompeting because of AI, they're outcompeting because they aren't bogged down by decades of technical debt and bureaucracy. At Amazon, it will take you months of design, approvals, and implementation to ship a small feature. A one-man startup can just ship it. There is still a real question that has to be answered: how do you safely let your company ship AI-generated code at scale without causing catastrophic failures? Nobody has solved this yet.
It's very simple. You treat AI as junior and review its code.
But that awesomely complex method has one disadvantage, having to do so means you can't brag about 300% performance improvement your team got from just commiting AI code to master branch without looking.
