Who's pushing it?

An interesting gathering last night where a group of us tried to come up with a list of people who are really pushing the envelope, in any field, in any visionary and (r)evolutionary way. Who's showing us the next level? Who's going beyond? Who refuses to pull back on the reigns when the galloping starts to feel dangerous? Who's at the edge of the galaxy? Who's tearing down veils of illusion like drapes in a motel room?

I won't give you the list of names we came up with so as not to bias your own. However, I will tell you that a flash of genuine horror arose upon considering this simple concept: We might actually be living in the most boring time in human history.
