But here’s the thing, many users won’t care for “warnings”, no matter how technically advanced they are. People just assume that pressing Y or other similar stuff is just part of the procedure without thinking twice.

I can agree with that sentence, but if a computer makes you type in “Yes, do as I say!”, you better make sure you’re not about to wipe out the human race.
Especially when it tells you within the same sentence that it is about to do something potentially harmful.

Like, I’m all for noob-proofing. I myself rarely read warnings properly. And I’m the type of idiot that closed the welcome screen on Linux Mint, because I didn’t need no stupid tutorial – shortly before spending 3 days having no clue whether it was even possible to install any software on this Linux thing.
But even I got tripped up when my computer asked me to type that in.

So, yeah, please do reflect on whether noob-proofing could be improved, but don’t take an entertainment video as genuine feedback. It’s simply more entertaining when the guy plays the more daring, more careless person.
