I guess you know that open power generation tenders are won by wind production and that in favorable locations the production price with solar is already at 3ct/kWh.
If it didn’t work out 40 years ago, it does not mean that it can’t work out now. There was telefon and then came the internet … there where wheels and then there was a car …
The good thing is, there is always change, but there will be also always resistance to change from established businesses and skeptics.
I invite you to have a look at recent news on wind and solar installations and perhaps you change your non-factual arguments.
