I don't know what you mean by dogmatic. Alternatives to electric are still the primary workhorses in most industries, but falling prices for batteries mean they are rapidly becoming more competitive.

My experience is that people don't have a good grasp of how effective electric is, and think it's somehow worse than the alternatives and winning via subsidies, which is not really the case today. Likewise for things like solar.

I imagine many businesses are hoping to put off their next replacement cycles for more effective, cheaper technology rather than incur big Capex expenses on soon to be obsolete and more expensive technologies.

dogmatic in this case refers to tolerating critical service disruptions despite strong signal that electric is not yet ready, when you could easily continue service with diesel, the mature technology.
