6.6 years ago, here on HN at https://news.ycombinator.com/item?id=177865 , was a link to "Scientists Create First Memristor: Missing Fourth Electronic Circuit Element" at Wired. User rms said: "I don't think we'll have any keeping up with Moore's Law. In 5 years memristor storage will be everywhere. IBM will develop memristor processors for the Blue Brain project." User TrevorJ said: "I fear that the huge inertia that is the software and hardware industry ... will keep this out of mainstream for 5-8 years."
In 2010 Engadget (at http://www.engadget.com/2010/08/31/hp-labs-teams-up-with-hyn... ) described a collaboration between HP Labs and Hynix. "Williams hopes to see the [memristor] transistors in consumer products by this time 2013, for approximately the price of what flash memory will be selling for at the time but with "at least twice the bit capacity.""
If anything, the optimism has become more pessimistic, as the future horizon lengthened from 5 years to 10. :)
