Go is pretty much a better-in-every-way replacement to that entire cluster of developer-friendly languages like Ruby, Python, Node.js etc. A startup in 2023 would need to have pretty good reasons to not start in Go.
For my part, my intuition is that my last project, in java, seemed to be more productive than the current project in go, and another current project, in python, also seems to be working better. But there are so many variables, it's impossible to untangle causality.
