Nim seems to be picking up a lot lately.
Really ? From what I see it survives OK but there is no real progression. I like what I saw of the language, and I'm regularly impressed by the productivity of the community relative to its size so I would like to see it more successful but I'm afraid it will not happen.
It is another niche language looking for a project to kick off adoption.
Not sure. I think it has a problem many languages have - too small a community. There is a lot of fragmentation in the last some years, I am not sure why, not just about nim but just look at how ruby has been dropping like a hot potato in the last ~3 years or more. I am so out of the loop that I could not even tell anyone what the young people are doing. Are there more who program than before? If so where do they go?
It’s growing but not a lot, I have some data here: https://pierretempel.com/p/nim-usage-on-github
Most code I write is still Nim though.
