Well I suppose what he said would have been offensive as a broad generalization of the abilities all women if he hadn't actually immediately corrected his statement to "some women"'which rendered it accurate. Some subset of nearly any group is going to have trouble making playlists. Even some technically proficient people might draw a blank on how to curate their own music collection.
I am no fan of the guy but I think he didn't mean any offense. He just is older and carries around an image in his mind of women and their interests and activities from a bygone era when women were, fairly or not, not known in general for interest in technology.
As for political correctness, I do think gender based political correctness is about to die an ugly death except in the workplace. I actually never really saw men being all that politically correct with women to begin with and the grumbling about it never died down.
I can't stand Donald Trump but he seems to have struck a nerve and people are more open about being sick of political correctness. The backlash is building momentum and we will be entering a new era of interacting. I hope it's a more productive one than what we've had so far.
As a female and a minority I am kind of tired of it, too, because I knew it was all hypocrisy and lies and that plenty of people who can't stand either my race or my gender were only being nice to me because of societal pressure. I mean attitudes can't have changed that much since I was a child when people were openly mocking my race. I doubt those people had some profound epiphany. They just learned to hide their contempt.
So I actually would be fine with people being open about their prejudices so I could avoid them and save us all a lot of bother. The world's a big place and I can find plenty of people who genuinely aren't prejudiced against some aspect of my being and I don't have to unwittingly inflict my company on those who are. Or they on me.
