Anecdotally, I can take on and complete the side projects I've always wanted to do but didn't due to the large amounts of yak shaving or unfamiliarity with parts of the stack. It's the difference between "hey wouldn't it be cool to have a Monte Carlo simulator for retirement planning with multidimensional search for the safe withdrawal rate depending on savings rate, age of retirement, and other assumptions" and doing it in an afternoon with some prompts.

I work at an Amazon subsidiary so I kinda have unlimited gpu budgets. I agree with siblings, I'm working on 5 side projects I have wanted to do as a framework lead for 7 years. I do them in my meetings. None of them are taking production traffic from customers, they're all nice to haves for developers. These tools have dropped the costs of building these tools massively. It's yet to be seen if they'll also make maintaining them the same, or spinning back up on them. But given AI built several of them in a few hours I'm less worried about that cost than I was a year ago (and not building them).

It's subjective, but the high monthly fee would suggest so. At the very least, they're getting an experience that those without are not.
