I guess I disagree about the legitimacy of the meme or any point that could be made from Go's "slowness to get generics". The only people who think that generics will be a slam-dunk net benefit for Go are the folks who can't articulate the costs associated with generics. The actual net benefit is so small and the error margins are so wide that it is entirely reasonable that Go didn't rush generics, instead prioritizing larger and more certain gains.
I mean legitimate meme as in, it is a point that is widely assumed true at this point, not as in it is actually accurate in its assessment. I never really thought Go needed generics.
