I don't know if new is the right term - maybe niche. A decade isn't exactly new.

I think your description of Nim is pretty accurate - but I also think a mention of its potential use cases in game dev / systems programming (and embedded systems programming) - where it can really shine - should be mentioned as well. It also can compile to objective-c. I don't think Nim is necessarily inspired by Python - I think it draws inspiration from a number of lanugages: Python, Ada, C, Go, Oberon, etc... It might be syntactically similar to python - but I definitely don't think it was inspired by it necessarily.

You might want to mention that the gc is plug gable and totally optional at the end of the day. Nim gives you access to a variety of programming paradigms and abstraction levels - if you want to manage memory yourself - you can. If you want boehm GC - you can have it.
