I think some of the apparently dogmatic attitude is from exhaustion. Usually (I'm not implying you) someone calling commonly accepted science into question are just waiting for a moment to drop something about Jesus, or Chemtrails or some other nonsense.
Or, maybe even more, recognize that the fun was in the developing, and not in the shipping. Don't stress over it not getting done. I have a ton of abandoned side projects, and I don't regret a single one. I also don't regret stopping them when they stopped being fun.
