Bill Gates: No one will ever have a need for Twitter.

From Wikiquote: Misattributed to Bill Gates

“640K ought to be enough for anybody.”

Often attributed to Gates in 1981. Gates considered the IBM PC’s 640kB program memory a significant breakthrough over 8-bit systems that were typically limited to 64kB, but he has denied making this remark:

“I’ve said some stupid things and some wrong things, but not that. No one involved in computers would ever say that a certain amount of memory is enough for all time … I keep bumping into that silly quotation attributed to me that says 640K of memory is enough. There’s never a citation; the quotation just floats like a rumor, repeated again and again.”
