If my manager said to me tomorrow: "I have to either get rid of one of your coworkers or your use of AI tools, which is it?"
I would, without any hesitation, ask that he fire one of my coworkers. Gemini / Claude is way more useful to me than any particular coworker.
And now I'm preparing for my post-software career because that coworker is going to be me in a few years.
Obviously I hope that I'm wrong, but I don't think I am.
