As an older Gen Xer (48), I’ve certainly felt ageism when I’ve simply applied for jobs — because they don’t know me. The best antidote I’ve found is showing up to tech community events and being as giving as I can with what I’ve learned through multiple tech startups over the decades. You have to turn what you have into an asset and make yourself valuable.
I do think a lot of it is a matter of mentality. I’ve always valued curiosity and a propensity for trying new approaches. I sharply recall the younger me being told to do things the traditional way. By still feeling that way, I welcome the new ideas of the younger generation. Those who lose that feeling push themselves into the category of inflexible and out-of-touch.
