I don’t remember anyone asking for a transcript of an unhinged crackhead rant, yet here you are

Knowing Nvidia, it’s probably supposed to display some sort of user confirmation prompt when run in interactive mode, but they forgot to disable it when doing a silent install.

Tough call. If it’s still flashing, you’re not frozen. But entire fresh OS installs barely take 15 min, so it’s hard to imagine that there isn’t something hung somewhere. I think you’re just going to have to decide if you’re willing to wait longer, I don’t think it’s ever really safe to hard reset mid os upgrade, but you’re likely going to have to.

But they’re ice dancers, so they should be in the clear, no?
