Actually, computer science conferences are peer reviewed. They play a similar role as journals in other fields. I think it’s just a historical curiosity that it’s conferences rather than journals that are the prestigious places to publish in CS!
Of course, this doesn’t change the overall picture of some AI work and much AI safety work not being peer reviewed.
I wasn’t sure if I was, but reading the guidelines matched my guess of what they would say, so I think I was familiar with them.
