I truly appreciate your answer, as someone that primarily does C#, but learned Java first back around 2003 to 2005. More so because my son is going to be learning Java next year in high school, and I know he'll be looking to me for help, and I'd like to at least be at the same language version as he's learning.

I've also been looking at Go quite a bit, especially from a lot of commentary even recently on YouTube, as well as plenty of time during work hours to experiment with languages I'm not familiar with. I've been deciding between Python and Go, and I picked up Python very quickly for the language, but ultimately I think it's the libraries and ecosystem around both that will decide it for me. Just good to see another vote for Go, especially when comparing to Java. I feel like I'm in the same boat as you seem to be, where it's all just syntax and learning frameworks, while having enough experience at this point to also pick up the smaller details while quickly being effective.
