This is currently one of the biggest impacts it's had on me: I no longer fear programming languages and DSLs that I'm not completely fluent in.
I've use ChatGPT to confidently produce jq programs, and Bash, and zsh, and ffmpeg scripts, and AppleScript - all tech I've mostly avoided in the past because I hadn't climbed the learning curve far enough to be confident with them.
To me it's an extension of that great feeling when you need to do something in an area you're not as fluent in and you find an SO thread that perfectly addresses your use-case, or at least gets you 90% of the way there. But with copilot you can do it from right within your IDE, or use ChatGPT to iterate on the results.
