The GP said it would have "bought Reddit a lot of time," the post I responded to said it was merely 2^31 implying that it wouldn't have bought them a lot of time, that's the part I was replying to (though I didn't word it clearly). 2 billion more values would have bought Reddit a lot of time.
I should have taken more time to read over both posts and respond more clearly though
Ah, I read the GP as a correction that it wasn't 2^16, but 2^31 values. The "doubling" was correctly stated, but the edit said they only had 2^16 values to work with. Almost certainly just a mistake in the post.
Right?
