I'd argue that *on average* comedy tends to deal with topical themes that stop being funny once they are no longer alive in the society.

Great satire remains funny even after everybody's forgotten the source (see: COLD COMFORT FARM). Just good satire fades with the thing being satirized.

Yeah. I just recently finished watching Have I Got News For You, which is some of the most topical comedy you can find (since it's about the last week).

Plenty of it is still hilarious even 19 years out of date. (And plenty of it falls flat, but it probably wasn't that funny in the first place)

And, weirdly, Cold Comfort Farm is itself mildly science-fictional.

I had a student ask me what the Anglo-Nicaraguan Conflict was.
