Agreed. I generally assume that any headline with the structure "X new thing could solve Y," where Y is a massive problem that everyone wants a silver bullet for, is clickbait. I've seen too many of them at this point.

Everyone wants a quick fix for climate change and pollution because it will absolve us of doing the hard work that the problem really requires. By all means, we should pursue such moonshot ideas - but like you said, it will be used to virtue signal some false idea of "progress" while the problem gets worse.
