The difference is AI tooling lies to you. Day 0 you think it's perfect but the more you use ai tools you realize using them wrong can give you gnarly bugs.

It's intuitive to use but hard to master

It took me a couple of days to find the right level of detail to prompt it. Too high level, and the codebase gets away from me/the tooling goes off the rails. Too low level, and I may as well do it myself. Maybe also learn the sorts of things Claude Code isn't good at yet. But once I got in the groove it was very easy from there. I think the whole process took 2-3 days.
