Just world fallacy.
People who are forgotten leave no legacy.
Most people don't even know how Wozniak is and the few that know probably see him as the geek that was Jobs' "slave".
You're equating fame with legacy then assuming Woz failed at his goals because he didn't end up famous.
Fame might matter to you, but its very obvious that fame doesn't matter to Woz.
As for legacy, Woz's legacy will be his work. My sister doesn't know Wozniak's name, but she loves her iphone and carries it everywhere she goes. Her iphone wouldn't exist as it does today without Woz. If thats not a ringing endorsement of his work, I don't know what is.
There are different definitions of success. Living and being able to do intelectual work until 95 (if this is what you want to do) could be perfectly one of them.
Yes. And I think, as opposed to Jobs, his legacy will be rewarded.
