I feel like the "demise of comedy" is overstated. Every time I see a comedian complaining about that, his netflix special is just a few clicks away.
Or at least know something about their experiences and come from a place of those experiences being real. I think a major reason that e.g. anti-LGBT jokes don't land the way they used to is simply that too many people know anything at all about LGBT experiences. Comedians can't get away with just making stuff up or leaning on cartoonish stereotypes, because it just rings hollow to so many people now. Likewise, "white guy does X like this / black guy does X like this" jokes are so dead that even jokes about the ineffectiveness of those jokes are trite.

Also, even when comedians are ostensibly telling actual jokes about "political correctness" or "safe spaces", it often comes off as somewhere between inept trolling and outright whining. Somebody could probably make a "Stand-up comedy bit about political correctness or Rush Limbaugh rant?" quiz.
