The same people who created a language with poor design decisions where superior solutions existed in other languages they could have simply used?
I see a trend here.
I bet they've designed and executed on more programming languages than you have :)
And yet hundreds of thousands of working programmers around the world are productively using Go while still continuing to ignore the supposedly superior solutions.
Here's another fallacy for you: false dilemma.
Hundreds of developers used Basic, Pascal, C, Modula-2, Assembly, Forth productively.
Maybe we should have kept using them, instead of coming up with programming languages that require a PhD. /s
