In case u didn't see this

Despite the exciting progress, Shulaker is also realistic about the prospects of electronics running on carbon nanotubes anytime soon. Additional research will be necessary to yield more sophisticated CNT-based computers, and the nanotubes are only one of several emerging technologies with the potential to replace silicon. Not to mention that any major disruption to the silicon-based electronics industry would be a formidable challenge. "I'd be naive to think that one fine morning, the industry will just wake up and toss silicon out the window," he said. "But I like to think that, maybe one day, Silicon Valley will become Carbon Valley."

He says "and the nanotubes are only one of several emerging technologies with the potential to replace silicon" One being POET I suppose

And like i said before which explains Intel ignoring us

"Not to mention that any major disruption to the silicon-based electronics industry would be a formidable challenge. "
