Oh, the delivery medium and medium are relevant. Not to you, that much is clear. But we've already established your viewpoint is an outlier. The person you're referring to is Bryan Cantrill [1]. For each expert like him, there are also Linux kernel experts, so I am not buying that one [2], sorry. He's been able to rant successfully in text, as you can read on the Wikipedia page. No idea why we'd have to see extremely long videos of him. I'm sure a shorter, to the point argument can be made by him. So if Cantrill (& friends) could sum it up in 10 min read in a 2018 sauce, that'd be great.

That's an unsubstantiated opinion not backed up by any kind of qualitative evidence.
