Indeed; but laughing at the scale of someone’s ambition (or vision?) might just mean that one’s own is too narrow or limited. After all, there are lots of narrow-minded, un-visionary folks out there.
Just because there’s an anti-Altman/-OpenAI sentiment on HN at the moment, it doesn’t mean that he’s wrong about everything, nor the people at TSMC are necessarily right.
Again, that it sounds ridiculous rooted in the conventional reality of today, doesn’t necessarily mean he’s wrong in his vision.
Again, the Russians laughed at Musk. The legacy space companies didn’t produce reusable boosters when they clearly could’ve, and people laughed at the idea until it was working. Etc.
(I’m not sure what relevance the NASA comment has; of course small underfunded startups need money to realise their goals? SpaceX needed NASA’s money to develop various projects faster, and NASA needed SpaceX to a) reduce launch costs and b) reduce their reliance on Russia for human launches.)
