gallium arsenide...."technology of the future, always has been, always will be"    :)

Gallium Arsenide has some uses as a radiation detector.

And some others uses where cost doesn't matter so much but low power usage and robustness versus heat does matter (think military in particular, and also some mobile phone circuitry I think). But it has not replaced silicon overall, which was the basis for the "technology of the future" phrase.
