I work with an aging boomers who complains about ageism all the time. He wanted an outrage salary which our employer couldn't afford. He asks for help but then insults everyone who tries to explain what ever concept it is he isn't understanding. He talks down to everyone and gets upset the second someone suggests he does something in a way he hasn't done before, don't suggest he use a framework or library ever because he will rant about how he never uses them and doesn't need anything new. He makes fun of anyone who threatens him. Anything newer than C is is a waste. Maybe this is 10% of Boomers but this is the experience I remember when I think of older programmers.
