I don't have proof of this but I suspect a table like that would fit within a terabyte

nostr:npub15fkerqqyp9mlh7n8xd6d5k9s27etuvaarvnp2vqed83dw9c603pqs5j9gr I honestly don't know how I would verify a valid sentence that has never been spoken. That seems gruelingly difficult. It is very likely that everything I've ever written is some sentence level permutation or recombination of something that someone else wrote.
