That's pretty definite by any measure.

Not really, sorry. The complaint still is that the announcements are of some magical huge improvement that is just not real. They might work in a prototype, maybe in a laboratory, or the thing just disintegrates after being exposed to water or something. Of course the results influence existing or future products, that's how the real world improvements come about.

By the time you modify the prototype (or whatever) into something that is actually real world production viable, with a reasonable lifespan and production costs, there's barely anything left in common with the hyperbolic announcement about fantasy stuff.

I stand by that statement you highlighted. And the fact that it isn't hyperbole. With all of these achievements being released as clickbait news articles, somehow when something exciting it's actually everything the market, it's crickets. Like solid state or "salt" batteries are starting to become products, seen any articles on those posted here recently? Or in news outlets in general? I haven't, but I honestly could've just missed them, or they didn't gain as much traction.
