That is a very good question. I don't think I've seen anything other PR spin on the subject that felt like it couldn't make up its mind how soon The Machine may be productized.

Last I tried to read one of those PR articles (probably posted here to HN), it sounded like memristors still exist as active research, even though that was supposed to be the gamechanging basis of The Machine, but they are The Machine branding software projects now and non-memristor product tech that is kind of memristor-esque.

But again, that's merely my mostly hearsay-informed, lay readings of tea leaves.

(It's starting to feel a bit like IBM's Watson where the "brand" The Machine has multiple meanings depending on which team/marketer/sales-person/researcher you are talking to.)
