>I wonder also how much of a driver new programmer productivity tools like copilot and ChatGPT are factoring into this. If your top 10% productivity workers just got a 30%+ productivity boost, that means you can easily shed the bottom 20% productive workers and still be ahead of the game.

I have been evangelizing GitHub Copilot (+ Copilot Chat) and ChatGPT Pro to my coworkers that include full-stack .Net/React devs, Python data science people, and embedded C devs.

Only the .Net/React devs have been sticking to both Copilot and ChatGPT Pro. The Python data science are using ChatGPT Pro but have dropped Copilot. The embedded C devs are using neither.
