You can also see a report on it from our campus news channel (the report on my talk starts about 4:18).
The talk seems to have been received well. I'm not sure whether I convinced anyone to take our courses or to become philosophy majors, but I can report that I had a lot of fun talking to about 50 or 60 people about Interstellar and philosophy! And now through the magic of the internet, I can discuss it even more!
See here and here for my blog posts on earlier attempts to think through these issues (minus my arguments about the meaning of death, which was new material added to the talk).
What do you think? Are death and extinction always bad? Will the human race survive forever? Would we want to?
