Of course GaAs is useful for microwave and DSP -- what I don't believe is
that it will ever become a mainstream commodity process like CMOS or NMOS
or even ECL. There will always be *some* customers willing to buy such
technology, generally DOD or other organizations with weak cost-control.

Perhaps I didn't make my reasoning clear enough. Given the usual development
timescale of digital electronics, I claim that if GaAs were really such a
smart idea it would *already* be rich.

GaAs is still poking around in niche markets umpteen years after the pioneers,
without ever having entered a regime of exponential capacity growth and
inverse-exponential price drop.

In this industry, technologies with such a profile are usually losers based
on a fundamental misreading either of engineering possibility or economics.
Niche markets and the enthusiasm of a few can keep them breathing stertorously
but they tend to end up having zero impact on the development of computing as
a whole.

Lisp machines. Forth machines. `Hybrid computing'. Thin-film memory. In 
software, APL...PL/1...Algol 68. Computing history is littered with the
corpses of these perpetually promising youngsters. Today, we have ADA and OS/2.
And tomorrow, I am nearly sure `commodity GaAs' will join this dismal list.
