You just have to go along with the idea that skin provides no indication of meatiness and that the two aliens are Ford Prefect types, then the short film lands just fine.
replyI guess. It's still hard to mesh with the idea they don't believe these humans flap their meat at each other, or that they do not communicate exclusively via radio signals.
replyIt doesn't match my idea that these are two energy/mechanical beings discussing a faraway planet from their spaceship or whatever, talking theory without actually seeing the beings they are discussing.
You've never encountered, say, a baffling code bug that couldn't possibly be caused by X, spent a day on it, and found out it turns out to be caused by X?
replyOh yes. But never dressed up as X! :D
replyMore seriously, what you describe is partly the short story. The short film adaptation doesn't quite work for me, for the reasons I explained in other comments.
