Since I've been in tech over 35 was "old", even among "senior" leadership. I had memories of when this wasn't the case (I even worked in a old style office where literally everyone had their own office with a door), but I thought maybe it was just a function of me being much younger then.
What's remarkable in these images is that there is a range of ages and at the same time it's obviously not a gerontocracy. I can't remember the last time I worked with someone that had gray hair.
The last several teams I've worked with I remember a constant sense of everyone trying to figure out what to do. When you look at resumes you can see why, nearly everyone has worked at one or two places and only worked for at most 5 years. On any of these teams everyone would still be considered "kids" with a lot to learn about patience and how to solve hard problems.
I seriously wonder what has happened to older people in tech, and sometimes wonder if one day I'll be taken out back and find out.
