Nevertheless I appreciate his efforts and just bought his book, because having an idea is way different from putting own money in it. He puts his own money to neuroscience, and does not compete with real scientists for government grants.

Other millionaires may buy yachts, or just spread "novel" ideas (e.g. Hyperloop idea by St. Elon) without investing their own money.

I appreciate and agree with your perspective on putting your money where your mouth is, but Elon is the last person to criticize in that context. He quite literally put all of his money into the problems that he thinks are the most valuable to work on (whether you agree with him or not).

False. He didn't put a single dollar into Hyperloop (idea that was researched since 100 years ago, and general conclusion is that it's not worth it, too expensive to maintain).

The book being from 2004 is kind of outdated. Nevertheless fun to read.
