It's a question of where to focus your attention. Consider the explore/exploit trade-off. Boring tech may be a little, well, boring, but that means you get to spend your limited decision-making capacity on solving your actual problem. If your actual problem is betting on a niche language early, then go for it! Otherwise, use the thing that balances your existing knowledge, interest, existing 3rd-party resources and has the right outlook over the expected timeline to get your outcome.

I think this site leans pretty niche.
