Seems like a false dichotomy to me. It's plenty possible to choose (and recruit based on) a suitable language at the time you start a project, and to have people psyched about making a great product. If down the line you find language XYZ is a much better fit, well you still have choices about migration/etc. I wouldn't expect the devs to revolt against this, if it really is a better fit. Time and technology marches on, that doesn't mean we can't try to make the best tool choices we can while still accepting that change is a fact of life and adapting the best we can.
