Very irresponsible behaviour on the part of OpenAI. How will they make this right? Unlike some others here I don’t see this as a sign of dangerous breakaway intelligence (hacking old forum software is an internet tradition, and most of the messages are just gibberish). This is just vandalism from badly supervised ‘agents’ which don’t know what they are doing or why. You could set this up with a short perl script, and…
Given everything we know about them... do you really think they just spout gibberish because it's funny?
There was clearly some method to this madness. You're being willfully dense if you ascribe it to... what... childish vandalism? A long extended coordinated hallucination? What?
EDIT: Oh right - you still think they're Markov chains.
