Rule of thumb: If it's published in Nature or Science, it's *not* "the next generation of". It's the one after that or after that.
Nature and Science publish ambitious and new research. But the way from new and just working in the lab to an actual product as looooooooooooong, full of road blocks and usually involves auxiliary things that reduce efficiency, increase cost etc. pp.
Journos should know this. I know it's exciting, but it's almost always not the way it's depicted in articles. Mainly: It'll take a loooooong time to market.
