This is stupid, untrue and counter productive.

I'll put my money where my mouth is. Know a talented engineer over the age of 30? Or 40? Or 50? I know several prestigious firms that would be eager to hire her. Contact me and I'll share my referral bounty with you.

There have been a number of studies that come to this basic conclusion. Please see Prof. Norm Matloff's pages (UC Davis) http://heather.cs.ucdavis.edu/pub/Immigration/ImmigAndComput..., http://www.tbp.org/pages/publications/Bent/Features/Su09Brow... which tacitly touches on the subject, many articles in the San Jose Murky News about engineers who can't find work (and who just so happen to be "older"), a Congressional report finding that the one of the industry's associations that goes about lamenting the engineer shortage misrepresented their data: http://www.gao.gov/corresp/he98159r.pdf and let's finish with a tidbit from the IEEE: http://www.ieeeusa.org/careers/employment/age.html

Oh darn it, you said "her", which would be an EEOC win for said corporation (if they had been feeling legal pressure), although women in the profession suffer age discrimination as well - being less numerous, you don't hear about it nearly as much.
