I've been watching Andreas' YouTube channel since very early on, and had some short interactions with him in his comment section, and I really believe that every one of the videos where he sits in his car and talks made a difference for me. They taught me a lot - and of course, after tens or hundreds of hours of watching him write code, my C++ looks quite similar to his.
I've never found the motivation or the desire to watch livestream coding. I had assumed that the value gained versus time investment wouldn't pay off. But then it was in Andreas' Igalia chat[1] that he said that showing the failures and getting stuck was important to portray. And now you're saying that you've (presumably) improved and can even identify similar coding patterns due to your investment. I guess I'm now finally convinced it's a good investment.
