There's a really cool show on right now, called Star Talk, showing an interview with George Takei, and the host has two guests-one is an astrophysicist and the other, not too sure (although she definitely knows her Star Trek). It's super interesting, and a lot of discussion about moral and social issues, as well as technology, then vs. now, and how it has all changed in the last 50 years.
Any Star Trek fans here?
ETA. it's on NatGeo Science
