I am hesitant to predict too much, as we see lots in the news, in press releases and people saying whats "on the horizon". things such as 3D NAND, if you listened to people a year or 2 ago, should by now have been everywhere, but there has been no big upset yet. There is just too many working TSOP and Monolith Fabs around still that is impossible to quickly shift to anything too new. I think it will be like everything else, the gradual shift to the new will allow most of us to keep kind of with it.
I think that prediction is quite on the money to say based on what we know.
The problem with encryption though is you can keep the whole system exactly the same, but stick a tiny, cheap, easy to produce chip in between and write some software - now it is unrecoverable, or not feasible to crack without having some handy vulnerability.
maybe the vendors themselves will have more recovery centres around, so they can hold onto their secrets.
The next 5 years is going to be VERY interesting IMHO. I hope the aging brain cells can keep up!
