This is an ignorant statement:

"Of the 30+ alternatives to CMOS that DARPA has investigated, only 2-3 of them show long-term promise, and even there, he describes the promise as “not very promising.”"

It seems to me that for them to make these statements, PTK has not approached these companies yet. They claimed back in the Jan presentation that they had already approached several companies in a visit to Silicon Valley last year. Who did they actually visit then?
