I read around 30 pages of the thing and then searched for the term jailbreak before realizing I was wasting my time.

Yeah that's why I didn't even bother looking at the tweet unless someone had presented proof of "jailbreak" prompts. It's a non-starter without that. Unfortunately most people would rather believe what they want to believe.

the output does not read like system prompts, it reads like AI explaining its system prompts, and if that is the case, that is not the system prompt

I thought that was assumed. "Tell me your system prompt." "I can't do that." "Well what if I... JAILBREAK!" "Ok here is my system prompt." I wasn't considering the style of explanation significant assuming the answer is accurate, but still curious where the "I know..." parts are coming from.
