We've heard things like that for centuries.
Some of my favorites:

1921: “The wireless music box has no imaginable commercial value. Who would pay for a message sent to no one in particular?” Associates of David Sarnoff.
1926: “While theoretically and technically television may be feasible, commercially and financially it is an impossibility.” Lee DeForest,

1936: “A rocket will never be able to leave the Earth’s atmosphere.” New York Times.

I believe in people, that they will (with enough support) do the right thing. That's already happening.
In Norway, 85% of new car sales are EV's. Even in the US, which has become resistant to new technologies, 2% of the cars sold now are EV's - and that is climbing rapidly. In California, which typically leads the nation on this, 8% of new car sales are plug-in.
Solar is expanding like crazy, as is wind. The problem is no longer how to get enough solar or wind energy - the problem is what to do with all the power it produces in the middle of the day.
Coal plants are closing left and right in the US and Europe, and being replaced by gas plants (cleaner) and renewables (much cleaner.)
You can deny those things all you like, and predict nothing will ever work. Just stay out of the way of the people who are making it work.
