gollark: Hmm, can you *fail* the 3-hour alcohol/drugs test somehow?
gollark: That sounds like a very effective way to make people not do alcohol and drugs!
gollark: I think there actually is good stuff available for language-y tasks - GPT-2 and probably some earlier neural network things.
gollark: > this is so difficult. I am programming an AI and my AI can react but it can't think. It is impossible. Anyone have any solutions<@301477111229841410> ... what do you mean? General intelligence is still a very unsolved problem, so don't expect much out of whatever you're doing.
gollark: Fair.
