"400 bytes should be enough for anybody"

The 'B' in 400B is billion, not bytes. And the quote '640k ought to be enough for everyone' doesn't have evidence supporting Bill G said it: https://www.computerworld.com/article/1563853/the-640k-quote....

That said, it'd be a fun quote and I've jokingly said it as well, as I think of it more as part of 'popular' culture lol
