The presenter banging on the keyboard, seemed totally distracted for minutes to say 2 sentences. It doesn’t need to be perfect but that level requires way too much good will to not just close the video… There is nothing wrong to say, ok let me regroup for a couple minutes then fully jump in for your audience.
Your overall process is perfect: first try to solve it from the UI, then the console, then the magic sysreq key.
The fact that your kernel was not responding to the sysreq key could mean a couple things: is it enabled on your install? (cat /proc/sys/kernel/sysrq to check)
Before trying to understand why the kernel locked up, are you sure everything is solid on the hardware side? ie. Did you overclock anything? If yes did you burn test the PC on some GPU demo?
And égalité…
I have seen another contributing factor in CS: it is really hard for the management to keep a good senior to junior ratio ie. A lot of juniors are trying to enter the workforce today. It means that during covid and shortly after the companies definitely relaxed as much as they could the geographical constraints for senior remote roles, also being senior they trusted them to work remotely not needing too much direct supervision. And now it backfires when your company is in silicon valley and you ask your senior developer from the boonies Colorado to move to an industrial concrete jungle.

Literally every product. People feel so much safer after that :)
Oh you lost a screw … Let me see … That will be $3k for the screw but we do have a cool new iPhone too you know!
I see some UI elements reuse more that textures no?
