I’m sure he has it all backed up. He’s a technology guy, IIRC.He's not on Patreon, or wasn't the last time that I checked. He used to give us videos like this when we attended his class. I would love a way to support/sponsor/pay for this kind of content these days. Don't know if it's against YouTube rules to also sell videos of what you upload there (e.g. downloaded from another server, on USB drives, etc). I'd buy the USBs as would many here. Just worried about the day when YouTube decides to remove the content, in the blink of an eye. I should just ask him directly.
