Thank you for asking the follow-up question. I appreciate anyone on HN who asks another HN participant a follow-up question to clarify the factual basis for a statement.

To briefly respond to your question before I take my child to a doctor appointment, what has always jarred me about this FAQ is the line

"The main answer to this question is that the vast majority of high-tech H-1Bs are programmers, not engineers, and programming does not use math."

If this professor of computer science truly believes that it doesn't take much math to produce a competent programmer, he has a different definition of competent programmer from that found at some other computer science deparments, including most computer science departments overseas. There is a lot of industry demand for computer programmers who can program in a way that best takes advantage of what a computer can do best, by reducing a problem to its most mathematically correct representation.

I don't think a professor at MIT would dream of writing a FAQ with a statement like that in it about the computer science major sequence at MIT. There does seem to be a shortage of MIT-level programmers, even if there is not a shortage of UC Davis-level programmers.
