Of course not... see the link on the REAL story about transistors.
The limitation is not so much the lack of willingness to come up with faster CPUs, it's a question of both economics, and physical limitations.
1-It would be very expensive, to where no one could buy it. (Can you afford a Cray?)
2-There are still major issues with dealing in fast transmission of data. Right now, 10 GBps is about as fast as we can go, to transmit data. That's why the next wave is photonic: why do you think people are putting fiber optic lines everywhere? For fun?
The silicon design is getting to its limit, and we should know shortly what that limit is. Once reached, light will power the next generation of CPUs. Stay tuned...
