No, I don't thinkbit is that argument. I think the argument is "Rust has a really steep learning curve". Nor do they imply that everyone who has given Rust 3 months will like it.
I tend to agree with his argument though, I can see how a lot of Golang developers would really benefit and enjoy migrating (Iām one of them) but I think it also depends on the type of applications that you usually write.
This is basically the "Anyone who doesn't love my favorite movie hasn't watched it enough times" argument. Programming language design is a complex space, there are no "correct" opinions.
