It’s just a fancy version of previous tools. Imagine a coworker instead does a refactor by grepping the entire codebase and doing a find-and-replace.

Do they ensure that it didn’t accidentally overwrite something it shouldn’t have?

Or do they just throw up a PR and assume their little refactoring bash command works fine, then expect their coworkers to debug it for them?

The 1st one, of course, that is the whole point. AI is increasing the 2nd one by an order of magnitude. People think they shouldn't have to do the 1st one anymore.
