The theme of this episode is adventure! That's right, beginning with an adventure... in etymology! Exciting! After that, Bennett shares his experience playing the game Outer Wilds, a game with a neat gameplay gimmick that deals with space exploration. This naturally leads into a discussion of space exploration in the real world; is it worth it? Do the benefits we've gained from space exploration justify the time, energy, money, and lives we've spent in the pursuit of knowledge?
