A floppy disk is a fixed size. The number of thoughts human language can convey is infinite. English Wikipedia has 6.6M articles. The AI could drop a Wikipedia-sized batch of articles, expertly written and cross-referenced, every day, forever. At the same interval they could drop 100 million YouTube videos, expertly authored and hyper-clear.

So yes there might be an infinite amount they cannot convey, but there is also an infinite amount they can convey. I guess it's half-glass-empty test if you are happy about the infinite you get, or are just sad about the infinite you don't get.
