1. GPT-2 was built for generating text, not music nor programming languages. So this is pretty impressive. 2. The "too dangerous to release" refers to the text generation mode of GPT-2 and was mainly targeted at spammers etc. 3. Of course there was a hype component in it. They wanted people to start thinking about the question before it's too late, which they did. I doubt that we'll get any kind of attempted world control takeover by AI (unless someone explicitly tells AI to do it, at which point it's a guy trying to seize world control with the help of an AI tool), but even if the chance is very small, if you multiply it with the damage, you should at least start wondering about countermeasures.
