Heroes of the Future?

I'm going to do an article for futurist.com (newly re-done site, by the way - what do you think?) on "Heroes of the Future." It started with a panel of the same name for Worldcon. The panel was a bust (actually a fun conversation, but as many panelists and audience members - y'all know how THAT goes).

I know I'm going to include rich people and folk that want to help - our Rockefellers if you will (Gates, Google, Branson)

Scientists, who we'll need desperately to help with global warming

Leaders, if we get any. There's a bit of a vacuum right now, and a good leader would be handy - a Gandhi of our day

Who else from our time might the future look back on as heroes?
