This is a stupid article. Fuck Elon, but I mean who cares how he streams? He's streaming like that exactly because he's rich and doesn't need to give a shit. I find it funny how every suggestion is like "he should have paid someone to do it for him", maybe he wants to do it himself? This is entertainment for him.
Sure, he has zero taste or knowledge of streaming/proper gaming setups, but he doesn't care and neither should you.
This is my personal take. As long as you're careful and thoughtful whenever using them, they can be extremely useful.
