Never Mind Flying Cars...
...What about Gallium Arsenide processors?!?
These have been in development since 1984 to my knowledge with all the big problems solved 7 or 8 years ago. They are commercially available for mobile phone exchanges with speeds of 300Ghz and a record of 555Ghz in the lab. They use copper on GA rather than highly capacitant aluminium. You might need to use silicon as a buffer to the outside world (much like using a VAX between a PC and a Cray1) thats a minuscule price to pay with no tech needing development.
Just imagine it, no more polar bear killing render farms, so screw the spooks and military, there is no market there, sell it to us nice creative people!
