It is against the law to discriminate against workers older than 40 when you\u2019re hiring and recruiting. But a recent investigation by ProPublica and The New York Times \u2013 which spun off from those organizations\u2019 investigations into the role social media and advertising algorithms played in spreading false, Russian propaganda during the 2016 election \u2013 shows that Facebook, Verizon, Amazon, UPS and others are using Facebook\u2019s advertising algorithms to do just that.\nIf you\u2019re over 40 and looking for a technology job, the algorithms would prevent you from even seeing recruiting ads \u2013 even if you\u2019re incredibly qualified for the role. And in my opinion, that\u2019s age discrimination.\nDiversity isn\u2019t just about race, class, ability, sex and gender \u2013 it\u2019s about age, too. Excluding older workers isn\u2019t just wrong; it\u2019s counterproductive. You\u2019re losing out on institutional knowledge, skills honed over years of practice, as well as the opportunity to have older tech talent serve as mentors to the younger generations.\nWhile ageism doesn\u2019t get as much attention as racism or sexism or homophobia in Silicon Valley, it\u2019s just as big a problem, with older workers resorting to drastic measures such as plastic surgery to appear younger so they can land a job. And now, social media\u2019s making it worse.
