And, doing projects in domains I'm unfamiliar with (and those I am) is massively sped up by AI.
I learn to do these projects with AI - it's different than learning to do it without AI, and I don't learn some steps I otherwise would, because AI can do those.
But, I start and finish and use and polish so many more projects in so many more domains, with AI, than I could without.
And, starting and finishing projects is the point for me, not learning obscure stuff that doesn't help there, so, I don't feel like I've missed out on much. You might look down on it, but, if I have AI and you don't, I will bet on me to finish a project before you, better than you, in almost any field where we have similar levels of experience.
IDK about frontier-pushing-pursuits, though. I've written algorithms by hand that I doubt AI ever would have, in its current state... but, then, at least a few of those I'd given up on, for lack of time, and when AI came along, I was able to go back and have it finish them. But, for me, the work wasn't the goal, or even my own accomplishment therein - I just wanted the result. If your motivations differ, you might not find AI as fucking awesome as I do.
