I feel like the idea that "a million transactions per second ought to be enough for anybody" (not a quote, just a paraphrase echoing Gates for those who missed it) could come back as another storied mistaken estimate at some point. Just taking the human population as a starting point, if we posit that in the future, non-human entities will also be doing transactions, and there may be orders of magnitude more of those entities than there are humans, and the entities will be networked and operating at machine speed… I don't know, but it seems like the thinking on scaling needs to be even more ambitious.
