A lot of stuff now happens automagically

Nothing happens automagically. You need to specifically ask Copilot to do something.

makes it harder to see the reasons and structures and language of how it is meant to work

This I also don’t fully agree with. Like I mentioned, Copilot won’t automatically place formulas everywhere - it just designs them but you need to copy-paste them into the appropriate spots.

So, yeah, you’re not writing the formulas, but it’s not like the whole thing just magically appears.
