If your assistant is causing you to work more hours and only sleeping 4 hours per night, is it really a good assistant? I think I'd be firing an assistant that did that to my life.

I'm a big believer is not just doing something because I can. Could AI build me a personal suite of apps to manage my life in the exact way I want... maybe? Should I spend my time doing that, even if AI is writing 100% of the code? Probably not. Will it be better enough to justify the investment? No. When it breaks or has bugs, who has to deal with me? Me. What about the infrastructure? Another thing to do.

You can say AI is writing all the code, but if someone has to be there to babysit and guide it the whole way, it's still work. Less engaging and rewarding work. I mostly find vibe coding to be boring and frustrating, unless it can one-shot it, which it can only do for small stuff.

I use AI, but I use it in the same way I would use a search engine or a hammer. It's a tool to help do what I was already doing. Sure, it grows my capacity to some degree, but pushing that too far ends up being problematic, as I lose my ability to properly oversee it.
