I’ve found Copilot helpful for some research and queries where I’m not really sure what I’m looking for, or when I’m sure something exists but not its exact form, or exactly where it is.

It’s unclear what you’re intending to use Copilot for. I wouldn’t trust it for anything unattended eg answering an email for me.

Google doing away with cookies also conveniently shifts away most ad processing from their servers into Chrome (while killing their competition).

Pkcell for sure. Just be careful with your dingus!
