For me, this is very true. Most bioinformatics is done in python, but over the last ~4 years I've ported everything I do over to Go: https://github.com/koeng101/dnadesign
I'm just massively more productive, and the fact that I can read code I wrote years ago and fully understand what I was thinking at the time is amazing, and I haven't experienced that in other languages. I've learned other languages quite in depth, but with Go it is simple enough that when I write code, I'm not thinking about code, it is purely the problem being solved, and the code just comes out onto the keyboard.
Ironically enough, I've recently started porting my entirely-go bioinformatics package to be a python package, mainly because I realize I'm not gonna convince everyone else in my field that Go > python
