Well, great insight.I haven't thought about it. You changed my opinions. But as you know when you master your expertise after 10 years you can make a lot of money by investing.
These people are rare exceptions. I am just not sure if I can invent something so great as they did.
I am also interested in computer security. I would love to create OpenBSD-like user-friendly system and sell only hardware like Apple. But it is so improbable. Masses are not interested in secure system. They want a pretty and easy to use system. So it is really hard to work on things in which you have passion, interest and make big money as well.
My main tendency is to donate research. There are smart people who are short on money. I could pay for their education etc. Creating another Google is hard task, but make money for honest poor student is not so hard. It is quite difficult to make a decision now.
