AI bros consistently handwave away any notions of the material world imposing limits, because (spoiler!) it's a religion where you start from the miracle and work backwards. "Oh, we'll just set up fully automated robotic research labs everywhere!" Where will you get the raw materials? Oh we'll mine the asteroids! How will you find the energy to get there? Oh, the AI will invent new physics! (again without needing to run experiments). Et.c.

Didn't and don't mean to disparage anyone's medical struggles, but "a cure for cancer" is a well-worn strawman. One that's been achieved for the low hanging fruit, the higher ones are seeing steady progress (already before LLM chatbots, even!), the bottleneck isn't "intelligence" and to the extent there are socioeconomic (access to screening, treatment) or environmental/lifestyle factors involved the AI boom is likely just making things worse!

I'm sure Dario knows this, and it's anyway too pedestrian compared to the usual list of fruits of ASI. The text probably originally read "nanobots eating you alive and uploading to the cloud" or something, but they figured that wouldn't go over with the intended audience. "What do the peasants care about? Oh I know! Curing cancer!"
