The speaker considers the interviewer’s question visionary because it anticipates a future in which data storage becomes large enough that some data must be deleted.

“they have access to so much information by doing this thing he's doing that he'd have to delete some and when deleting information he'd have to spend energy which would then make sure entropy increases so even though we're not at the level where we can be Maxwell's demon I think your question is like very visionary towards like a future where we store so much data we have to delete some”
