I had to think hard about this, and I couldn't come up with something so obvious that it would be a no brainer to not use Nim.
__MatrixMan__ and SJMG have good points. If it's anything, it wouldn't be a technical issue in the language. It's like a Tesla when it first came out; it was obvious that EVs are the future, but they had less investment, less adoption, not enough charging stations, shorter range, and not a lot of certified shops for repairs. So naturally a lot of people held back until it became mainstream.
The issue is, will it become mainstream one day? Maybe, maybe not. But I'm betting on it myself.
