The way some of these companies are solving this problem is by hiring old engineers here in the states. I went to give a talk at the Silicon Valley office of a very large Chinese company that you've heard of, and almost everyone in the room was over 30 (and Chinese). The few white guys in the room were mostly over 40 (probably over 50 even).

There was one woman, who was a young Chinese lady, and no one of any other color. This was in a group of about 100 engineers.

Oh and at the end they offered me a job. I was 38 at the time.
