I often find it hard to believe that a single person can make much of a difference in such intricate problem domains as chip design but in his case the evidence is overwhelming. Also goes to show what a shit show Intel has become since even he was not able to right that ship. I think in the CPU space it will be all ARM and RISC ten years from now and since Intel never really managed to become a dominant player in any…
Novel development in a complex problem space isn't something one can just throw manpower at and expect progress. I'm sure that a certain amount of his fame is due to being a famous architect, as name recognition always compounds. There's no way he's more influential than the rest of the industry combined (shoulders of giants and whatnot), but I would be hard pressed to find press recognition of other hardware engineers. Still, he is undoubtedly exceptional.
For example, one could round up as many scientists as they could find in 1900, but there is no number that would guarantee the progress made in theoretical physics by someone like Einstein alone.
