Take this article. It says that some companies ("dozens") place some ads targeted at younger audiences.

NOTHING indicates that it's a major trend or that they do this a lot. The article is written because of a legal issue. But if you only read the comments you get an impression of the streets filling up with discarded old ultracompetent programmers.

I don't have the whole picture either of course, but a long life in the industry gives me the impression that it actually mostly does work just the way you think it should.
