The killer product being the lying machine or the deleting working code machine? I think there's a small number of people for who these tools really fit into their workflows but they are not universal so there's limited growth and they're already wildly unprofitable.

Because "user-friendly" UIs have successfully, market-wise, killed normal computing (like under Windows 2000, or even like "advanced users" under Unix-likes do, nothing complex or hard, not even harder than the "user-friendly" way, but very scary when you're conditioned to think it's not normal to edit configs or run commands ; it's very stupid, one would think editing files or entering a few words and pressing "enter" are not godlike powers).

That had the (subjectively) positive results of enshittification and monopolized Web.

Replacing the "user-friendly" UIs with mobile-like UIs mostly failed cause those are simply inferior.

But agentic AIs seem the way to go so that the typical user would never ever try to form preferences of how they use things, their own habits and processes.

And yes, the bigger the heap, the easier to hide a microphone there, and each such level of obscuring and generalizing control makes the heap order of magnitude bigger.
