I don't even see much reason to use Cursor. I am used to IntelliJ IDEA, so I just downloaded the Claude Code plugin and basically now I use the IDE only for navigating in the code, finding references and reviewing the code. I can't even remember the last time I wrote more than 2 lines of code. Claude Code has catapulted my performance at least 5x if not more. And now that the cost of writing test is so minimal I am also able to achieve much better (and meaningful!) test coverage too. The AI agents is where the most productivity is. I just create a plan with Claude, iterate over, ask questions, then let it implement the plan, review, ask to do some adjustments. No manual writing of code at all. Zero.
