I mean, as far as a corpus goes, I suppose all text on the internet gets pretty close if most books are included, but even then you’re mostly looking at English language books that have been OCR’d.

But I look down my nose at conceptions that human knowledge is packagable as plain text, our lives, experience, and intelligence is so much more than the cognitive strings we assemble in our heads in order to reason. It’s like in that movie Contact when Jodie Foster muses that they should have sent a poet. Our empathy and curiosity and desires are not encoded in UTF8. You might say these are realms other than knowledge, but woe to the engineer who thinks they’re building anything superhuman while leaving these dimensions out, they’re left with a cold super-rationalist with no impulse to create of its own.
