Forget code. This is not the Github Copilot, aka. ol' completion model powered autocomplete. I'm talking about Windows Copilot, i.e. something more like Bing Chat, except it's fully, deeply integrated with the OS. See the demo video. It's not meant for techies like us to ask it to write PS scripts for us. It's for any user to be able to ask "how the fsck can i make the text smaller?", or "where the fsck did my document go?", or "what the fsck am I even looking at?", and the Copilot is supposed to tweak relevant system settings for you, find and arrange windows, summarize or edit documents you have opened - and suggest what software you could use or install (this is where monetization will enter the picture) to do the thing you asked it how to do.

(Also, I found GPT-3.5 helpful with PowerShell; didn't have a reason to try out GPT-4 on PS yet).
