I honestly think I prefer to believe that each of us has the power within us and with enough determination a team of regular people can accomplish amazing things. Those make for great, inspirational stories and they're actually true in the case of John Lassiter (fired from Disney as an animator), Jobs (not a standout until Apple), etc.
And I do think great computing an animation would have happened anyway without them. But would we have Pixar without Lassiter? Apple without Jobs? I honestly don't think we would.
