About half of those memes have been deemed impossible to prove or debunked as false. Several were originally posted as "interesting lists" filler material in tabloids. In other words, likely made up.
some of them might not be real quotes, but Bill Gates is also credited with the statement "no one will ever need more than 640k of memory", but he never said that either. instead Microsoft and other companies found ways to go beyond 640k. the 640k "limit" was a hardware limitation imposed by the design of the IBM PC. there was actually 1 Meg of address space, but between 640k and 1 Meg was where hardware such as video cards, etc... were mapped to.
