“By 2030, if we don’t have models that are extraordinarily capable and do things that we ourselves cannot do, I’d be very surprised,” said OpenAI CEO Sam Altman in an interview published by Politico in September. After this year, “I think in many ways GPT5 is already smarter than me at least, and I think a lot of other people too”.

The AI advances we have seen this year could “set the world on a path of explosive growth”, said The Economist. “The picture that is emerging is perhaps counterintuitive and certainly mind-boggling.”
