The only fair way to compare the cost to solar and wind, is if wind and solar producers would have to make power guarantees 24/7 and cover the cost of the production gaps (hint: this makes solar and wind very expensive).
I've had a long career in software and my conclusions is that if soft skills are valued over hard skills, the organization is already captured by talentless engineers and leaders. There are holdouts in the world, where execution is king, find those places and run away from soft skill fortresses. This is more true than even with LLM-amplified productivity.
One of my kids are particularly brilliant and what I found is that the combination works best, "you are smart therefore I have high expectations" AND "without doing the work being smart doesn't matter". Together this creates a self image of the capable doer.

This is based on my personal experience, I used to ride trains for travel a lot. I grew up in Europe and lived there for 31 years so this is not based on ignorance.
