How would this affect future generations of ... well anyone, when they have 24/7 access to extremely smart mentor who will find solution to pretty much any problem they might face?

Can't just offload all the hard things to the AI and let your brain waste away. There's a reason brain is equated to a muscle - you have to actively use it to grow it (not physically in size, obviously).

I agree with you about using our brains. I honestly have no idea.

But I can tell you that, just like with most things in life, this is yet another area where we are increasingly getting to do just the things we WANT to do (like think about code or features and have it appear, pixel pushing, smoothing out the actual UX, porting to faster languages) and not have to do things most people don't want to do, like drudgery (writing tests, formatting code, refactoring manually, updating documentation, manually moving tickets around like a caveman). Or to use a non tech example, having to spend hours fixing word document formatting.

So we're getting more spoiled. For example, kids have never waited for a table at a restaurant for more than 20 mins (which most people used to do all the time before abundant food delivery or reservation systems). Not that we ever enjoyed it, but learning to be bored, learning to not just get instant gratification is something that's happening all over in life.

Now it's happening even with work. So I honestly don't know how it'll affect society.

Just because you have every instruction manual doesn't mean you can follow and perform the steps or have time to or can adapt to a real world situation.
