Sadly, I'm not sure I can make this as I've just come to know about it. But MacArthur Genius and personal hero Richard Stallman is going to be speaking at UCB next week.
This will be thought provoking for sure. If you don't know all about Stallman (or rms) go read the the excellent wikipedia article on him.
One thing missing from the wikipedia article was that he had to hire someone to type for him because emacs (which he created) gave him severe repetitive stress injury. (Emacs is famous for "chorded" commands that wrap your fingers into pretzels.) Or maybe this was just MIT legend.
