I keep hoping for better answers to this. Your longer answer is frankly just as disappointing.
"AI doesn't take showers" was particularly unconvincing. An army of AIs can ruminate on a codebase indefinitely. They can explore a possibility space at scale in a number of dimensions beyond most humans. How do you think these math problems are being solved? Code is largely verifiable and testable, most of the things that are hard to test is with human interaction. But humans will increasingly be out of the loop.
Most apps are not very useful. Most startups fail. Most companies are copying each other. There's a reason AI is so good.
Trust will be solved with mitigations. There will be inventions in this regard like breakthroughs in formal verification and adversarial LLMs to hold the automations accountable. At a certain point AIs will be trusted more than humans. AI has no free will. Humans go rogue all the time. You can't wipe their brains or reset them or turn them off. How many AIs have shot up their workplace? I just am kind of baffled by people who say AI can't be trusted or controlled as if humans can be?
The question is about outcomes. Costs and benefits. It seems obvious to me within 10 years unless you are within the top 1% of software engineers an AI will make more economic sense than you on a basic cost/benefit breakdown. Maybe a few of the top 10% hang around to certify certain critical paths so if the AI makes a big enough goof you are around to have the rope be hung around your neck.
The end state of capital is automation of everything. The humans actually doing interesting things aren't making "prototype apps" or being "project managers" they are building these AIs or coming up with ways to engineer UBI and a future where knowledge workers cease to exist without the entire economy collapsing.
I'm sorry but it's just not a very good answer. Thanks for trying though.
