Well, I think some of the other responses were a bit harsh. Although, I do agree that having Python and JavaScript on a 2021 list of up-and-coming languages is unnecessary.
Like you, I haven't messed around with Go or Solidity. I'll probably skip Go unless I find myself in a position that requires it. I just don't see the point in stacking up more syntax knowledge when I can learn it a lot faster when I actually have a problem to solve.
Solidity interests me though. I've been mulling over Blockchain development for a couple years now. Haven't found myself in a position that requires it as of yet, but I think it's a good time to experiment on my own.
You mentioned Blockchain isn't always Crypto. I think an article about the things you can do with Blockchain aside from creating coins would be really interesting.
