I mean, he's a retired guy with new hobby, it wouldn't seem too out of the question that he spent a good chunk of time following tutorials for things that have plenty of tutorials out there.

Yes but he's obviously far more qualified. LTT was trying to give real-world impressions of someone with a technical mind but also zero experience with Linux. Yes, he did something dumb and was clearly not paying attention, but also he never should have been put in that position in the first place. Every distro probably needs to automatically force an update as part of the setup process.

I remember when he played minecraft and made a redstone contraption to auto-feed villagers or something. He started by saying that he wasn't good at redstone and proceeds to show something so complex that I would have to follow a tutorial to make it.
