I think he was saying:
By the time the new chip is ready, that will be 1.5 years which implies 5x growth if we assume 3x per year. So; by the time OpenBrain is ready to build the next datacenter, we’re in middle/late 2026 instead of beginning of 26.
Aside from that, the idea that investment will scale proportionally seems like a huge leap of faith. If the next training run does not deliver the goods there is no way softbank et al. pour in 100B.
Which no one does anymore because it doesn’t work...
