I hear you, the last thing I want to feel is dread when implementing something. But recently my priorities have shifted a lot with regards to using the fancy, the new and the shiny. Sometimes I just want to end the day with getting something done and going home with the feeling of satisfaction and having achieved something tangible. Again, context matters with these things.
And with regards to employee retention, I would rather bet big on benefits (paid time off, parental leave, etc.), reasonable working hours (4 days per week), achievable goals, great communication, democracy and good team cohesion. I have a feeling this works for a lot of people. If a language is the only thing that makes you stay, by all means find a place that truly makes you happy in that regard. All I am saying is that there are a lot more variables to worker satisfaction.
