I watched about 8 minutes total out of the 20+, which means he's very good (because I don't normally watch videos like this - I went to elementary school and learned to read, and it's much faster). He makes the point about USB 2 early on, after which I watched what I watched just because he's articulate and entertaining.
However, a guy I'm quoting without his permission wrote this:
"Louis has some great content on his channel and occasionally he does like to rant.
He does component level repair on Macs. So a lot of his ranting stems from the Right To Repair movement.
He has been sued by Apple in the past and is often used as an expert witness regarding Right to Repair cases.
I wonder how many people in the Mac world are actually using USB 2 interfaces to begin with.
I do know a few. At least one person has an M-Audio M-Track. She just recently got a 2018 MBP that has the T2 chip.
I helped her set it up and so far she has had no complaints about audio problems.
I realize that is anecdotal, but certainly evidence that the problem is not universal.
Makes me wonder how much drivers play a role in this issue.'
