The whole point of this endeavour of mine was to examine what this person had said about these brilliant minds realizing what they would by the time they were 20, but unfortunately, with these short bios, we only see, generally, when these folks acted upon pre-existing ideas. For instance, when did Quentin Tarantino begin piecing together his plan/ideas about the world, career, film? Only an in-depth look at these people would yield such.
With that in mind, I have here a list of the age at which each person listed here so far made their first big achievement/whatever, listed next to the age. Then, I’ve averaged out the ages to see what we end up with for the mean age of the innovators.
Bill Gates- 20 Alltair BASIC Program
Paul Allen- 20 ditto
Larry Page- 24 Google
Sergey Brin- 24 ditto
Steven Spielberg- 29 Jaws
George Lucas- 28 American Graffiti
Quentin Tarantino- 31 Pulp Fiction
Kevin Williamson- 30 Scream
Linus Torvalds- 22 Linux
Michael Dell- 19 Dell computers
Augusuc Caesar- 25 took over Rome
Warren Buffet- 31 First million dollars
Jim Carrey- 30, between Living Color/Ace Ventura
Sam Walton- 27 Wal Mart
Ralph Lauren- 28 Polo clothing
John Rockefeller- 31 President of new Standard Oil
William Randolph Hearst- 23 takes over San Francisco Examiner
Oprah Winfrey- 32 show
Walt Disney- 35 new Disney Productions takes off
Ted Turner- 32 begins assembling broadcast system
Melnichenko- 21 MDM bank
Sergei Popov- 27 coal mines
Wong Kwong Yu- 18 store
31
25
25
Howard Stern- 32 national radio
Peter Jackson- 26 Bad Taste
Will Smith- 22 sitcom
768, which divided by the 29 people =26.5 years old
That means 26.5 years old for the first big achievement, I should reiterate, not for when they figured out what they would.
