> The AI of today can and if everyone knew about it, they would be using it.

The AI of today absolutely does not add 0.5x, I'm using cursor and copilot and they still are usually just a fiddly tool which gets it right half the time. Anything complicated enough to need me to review its work takes longer through series of prompting and correcting its work than if I did it myself, and anything trivial enough for it to one shot its not saving me much time on anyways. All for a costly monthly subscription.
