I had a similar experience. I took a very small project from Python and turned it into Nim: it was about six times as fast to run and took roughly the same amount of code in both. I have plans to learn more but this article is actually a little more fuel for my fire as I think one of my next explorations would be transferring and running code on other systems. If portability is as easy I could see this being used for some work tools I am building. We will almost surely never replace the current language all the major code is written in, but for small self-contained tools it would be great.
