I presume working on the above software burned some deep scars. Their switch from Go to Rust is motivated by this kind of issue.
(To be honest, I also stopped writing Go for fun because these kinds of paper cuts build up. I enjoy Go when writing stuff in its sweet spot - dealing mostly with network bytes in a server environment of my choosing. For me, venturing too far out of that domain is joyless, but not exactly painful.)
That stance is very much real, even if it's best described by gesturing at half a dozen examples. And it's nothing new, really. It's just Worse is Better all over again. I think it's instructive to see how it plays out in Go.
This rant is one-sided, but it doesn't pretend to be otherwise.
The author presents things about the language that they don't like. How on earth is that "toxic?"
Have we reached the point where "toxicity" is just "things I don't like hearing?"
The article isn't in the slightest bit toxic.
Just because you disagree with it doesn't make it toxic.
