I watched some of his intervews, most of them interviews included in documentaries about Steve Jobs. Steve Wozniak came across as someone naive, and easily swindled from his money. He also had his own story about Steve Jobs commission an engineering job for him while he was with Atari. Jobs never paid him the full amount.
He does appear to be a bit careless about money as well as what he puts his weight behind. This may also be the reason that despite his technical acumen, Woz didn't really build anything great on his own after Apple. This is also one of the reasons that the project Efforce being talked about in this thread doesn't derive a lot of legitimacy from Steve's association. Coz he basically just finds the idea amazing and has put his name on it, yet, it is wholly possible that he doesn't really understand the business viability of crowd-funding efficiency infrastructure programs.
He has a lawsuit filed against him by someone who is claiming copyright infringement about the idea of starting a technology training institute inspired by his name. While defending himself he says this:
“One thing I avoid in life is anything having to do with money,” Wozniak said according to the filing. “I just don’t look at it... I wouldn’t know how much is in our bank account. My life is very different than most people.”
Those surely aren't words of an astute businessman. Yet, when he says that Bitcoin is a mathematical miracle, i think we can all agree with him.
