Its weird to me that this is supposed to be THE end goal. Having an agent that does "everything" for you sounds like no paradise. It sounds depressing.

Maybe there is value in expending effort and actual creativity.

Not sure why you’re talking about it doing literally everything for you. I’m sure you can imagine a scenario where it handles annoying things for you and leaves you free to do things you enjoy instead.

Maybe it gets 10 car insurance quotes for you based on 4 models of car you’re considering.

Or figures out which psychologists in some travel distance of you actually take your insurance, are taking new patients, and what availability they have.

I can think of a ton of scenarios where a capable and reliable AI agent could make my life simpler.

I think this is just the flaw in the sales pitch. They want it to be inevitable so they describe as doing everything. That way it will appear more useful to more people. If they presented a realistic view of what is going it wouldn't be as interesting.
