Oh no. That's one possible inspiration. Another would be Braintree IPOing or continuing as a company providing an alternative to Paypal's BS I constantly read about while guy continues to make tons of money or get rich. Then he invests in hard problems we're likely to solve where we have the necessary foundation to begin to achieve the stated goals.
Instead, he got rich selling off his good company and now has money to blow on stuff like this. Good for him. Still inspirational with Braintree's early work still something I'm going to cite. Just still worth critiquing for where it went or is going wrong so next bootstrapper considers better alternatives.
Also, realize the irony that you don't like us criticizing what he did with Braintree or where the money is going while Braintree itself owed its success to correct criticism of how successful payment companies were doing things & where their investments were going. He pointed out the problems, showed a better way via his offering, and now we're talking about him instead of them. ;)
That's compatible with my comment. It proposes alternative to the path he took that other bootstrappers with utilitarian bent might find interesting. It doesn't require him personally to do anything. I even said his success was "good for him" in terms of efforts in and result achieved.
"You act like you rose him out of the ashes to save humanity"
You made that up. I explicitly said he didn't. His goal was to get rich. It would take more selfless individuals to do lasting things for humanity. It will take majority of humanity working together to save humanity.
We don't have to guess about his motivations, though. It's in the article:
"For Johnson, the quest is innately personal. His step-father has early signs of Alzheimer’s."
He and his step-father are suffering through the effects of Alzheimer's. He definitely has personal gain from a treatment that would work. There's a clear selfless angle on helping the step-father. He probably, after personally experiencing it, also would like to prevent others from going through the same thing. That's my guess. Respectable motivations for sure.
