Strongly disagree. Claude Code is the most intuitive technology I've ever used-- way easier than learning to use even VS Code for example. It doesn't even take weeks. Maybe a day or two to get the hang of it and you're off to the races.
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 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.
I actually don't use it in the terminal, I use the vs code extension. It's a better experience (bringing up the file being edited, nicer diffs, etc.) But both are trivial to pick up.
