I've been working in high tech for a long time and have seen several revolutions
in high tech. You are quite correct. In the short term the demand for our
services will become quite high.
But, in the long term (What's long these days? A few years?) the winners are
those who keep the customer clearly in mind --> best features, newest
innovations, lowest cost, hit the market window. Customers simply don't care
about SI. They want results, not elegant technical discussions.
Even without unecessarily fast edge rates there won't be enough SI engineers to
go around for years. The exciting part about SI is that interest in it and SI
engineers is exploding anyway.

Roy,
Most who understand die shrinks understand why edge rates increase. And like
yourself, most do not think that semiconductor manufactures are intentionally
making our jobs harder. And certainly I agree with you on who the
winning team will be.
But how does that support your contention "that increased edge rates as a
consequence of semiconductor die shrinkage, not application need, is the
opposite of job security for SI engineers." It seems to me that this causes
greater need for SI engineers. Where did I miss the boat?
Regards,
Aubrey Sparkman
