Well, if you keep working on shitty tasks (because you assign them to yourself) and keep being interrupted, only for your product to depend on the hazards of the market, you will get burned at some point if what you ship fails for reasons that don't depend on you or the team and people leave as a result.
I honestly hope it will not happen because you seem like a great Lead, but you can't say this scenario is not a possibility.
I think lots of programming languages are been created, and the vast majority of them fall into obscurity, but some have nice features and grain a bit of traction, which is what is happening right now with Nim. If you forgive me the comparison, I would say that Nim is to the programming languages what Flappy Birds is to the video games: a successful product built by a talented programmer in a place where lots of people try their own - of course, the analogy is not completely right since the barrier to create a programming language is much, much higher than to create a small video game.
