Ok, I guess I deserve ad hominem if I hinted at it.<p>I grew up in Brazil and that makes you more cynical then growing up in California.  When you live in a place like that, you learn that just because something sounds good doesn't mean it is.<p>I'm also a graduate student at MIT working on cancer nanotechnology.  When not being provocative online I spent all my hours in lab developing tools for oncologists to detect cancer earlier and treat it better.  I have a patent from my undergrad research at Berkeley for a needle-free drug delivery device that is moving through animal trials to hopefully make injections less painful for people (even kids - think of the kids!).<p>I also spent a ton of time making the MIT Clean Energy Prize into a national organization, to help students across the US get access to capital and mentorship so they can start clean energy companies when they graduate.<p>Is that altruistic enough for you?
