For what it's worth, go is still "new" in my book. I'm seeing 2012 for the first 1.0 public release. In contrast, we've had python since 1991. There's a large number of programmers who haven't had a chance to be exposed to go. I have used it, and enjoyed it. I'd expect, but haven't confirmed, that python has a larger collection of libs (especially long tail).

Although, looking now I'm seeing a short support window for go releaI. That can hurt uptake.

Like go 1.18 was released 2022-03-15 and will EOL Q1 2023.

Lots of projects want long term support so that churn isn't desired. I'm curious how teams handle that.
