I think it's now all about IBM, Buz. They''re investing billions in graphene research. According to Tom, they are now our friends. Will they invest here? If they see promise they will.
Buzz, I really I'm trying to look even further ahead. When I was talking to Steve Cordovano is was clear the fabrication goes from difficult to extremely difficult. (see for example the device roadmap) http://lightwavelogic.com/product-development-roadmap/ The slot waveguide Modulator is a tricky one.
In time this kind of fabrication process will be as easy as it gets. Also, what's beyond CMOS processing? All-Optical? By that time it looks like the current fabrication will be something from the stone ages.
Someday I will stand in such a facility and see the plastic/glass rolls with printed/lasered computer chips coming down and being cut, with hopefully our material INSIDE.
