Wrong answer. Thanks for playing. We have some lovely parting gifts for you backstage. Buh-bye...

That's why really high speed circuits don't use 45nm or less MOSFET technology, they use vacuum tubes, because everyone knows that parasitic capacitance doesn't matter and electrons move faster in a vacuum...
The actual journal article is good, it's the summary / news article that's brain-dead. They mention that tubes are only good for high-power applications, and nowhere do they mention using this technology to accelerate computing. Unfortunately, you can't read the actual article without a journal subscription, and due to copyright, I don't think I'm allowed to post the PDF here.
