Great, congratulations. Now figure out how to use the tech without increasing per TB costs and find financing for that with large enough ROI so that the capital that be cares. Seagate already ships 24G HDDs at 20 Euro/TB, whether you want to call a step up to 30 "drastic" I'll leave up to you.
Meanwhile, current NAND chips aren't using EUV. The industry can piggyback off the investment and experience of logic chip manufacturers, HDD manufacturers can't. Synergy and all that.
It can also be true stuff presented in an unbiased way. There's a disconnect here between the proper definition of the word, which is perfectly neutral, and its connotations because the what secretary for tsunami safety doesn't call their stuff "propaganda" but "public service announcement". Still the same thing, though, the tsunami safety secretary is trying to persuade the audience to not be stupid and get to high ground as soon as the sea recedes. Very much pushing an agenda, they *gasp* want people to survive and *gasp* use communication to achieve it.
