I think you're underestimating how badly it taught them. I see a lot of developers (when interviewing) that are unable to reason about code.
Lot's of people learn how to cook by following recipes, but they don't try to get work in catering or running restaurants. That requires a different level of understanding.
SO was the coding recipe book. It was fine for hobbyists. Not professionals.
So it's not dogs and cats this time. Ok.
Investors are interested in projects that start making money quickly, and wind is pretty good at that over other power infrastructure. Trump is going to be fighting the free markets that he holds so dear.
