This guys brain is so wilted he doesn't know that restore points are a security issue. He must have been using linux so long he forgot what malware can do. He's an idiot btw. Restore points are the easiest way to get rid of a nigerian prince!! 8D
I've been using linux for more than a decade, maybe two decades at this point. I still know that those are a necessity in windows for security. The same is true in linux but you usually use a secondary backup as a restore point. If you do at all.
Youtube is a wonderland of trash and idiots. It is and will continue to result in that idiocy being given money and pushing out anyone more intelligent to make that stupidity solid and stable in society. You can figure out the rest. This is why youtube is more and more like a TV as we go. BTW, the difference in the past is that there was some iota of the opposite to learn from in the past. That has been wiped out. And I'm using the term wiped out intentionally as that is what literally occured.
BTW, I get horrific dread and am repulsed by anything requiring a download that is not a major companies video game or very well known software. And that is only to run with proton. I can't stand people who think it's safe to download anything...
The only old computer I would run would be an old dos machine with windows 3.1 for retro games if I cared. But as that was pre internet I wouldn't have to worry about viruses. Unless I hooked it up to my computer in a network... Nah, just use the monitor. Software isn't convenient enough yet to make me want to do that. At which point I would hope it's convenient enough to make dosbox or an alternative work out of the box.
Also, the guy is using so many facial expressions because he has no idea what he's talking about. He's relying on emotion to express something and does not have sufficient knowledge to be giving advice on this level. If it's a youtuber it's the bottom of the barrel of an example of wahtever it is. Engineer, lawyer, idiot on the internet. (BTW, much better exist of all of these examples outside youtube. ;p)
