But then, somewhere along the line, that changed. In the mid-2010s, you started to see these companies talking about diversity. DEI initiatives became a thing. Progressive benefits came into play. I remember covering a lot of announcements about parental leave. What changed?

As these companies got larger and more structured, they grew up a little bit. They realized that they had to have HR departments, they had to have management systems. They were too big to just run on the ideas of whoever the genius founder happened to be. So there were more and more people coming into the industry to impose some sense of structure and rules on what had previously been pretty freewheeling.

At the same time, tech companies also came to embody this new idea of what an office could be, because they brought in more structure and more of a sense of rules, but they maintained a sense of fun and playfulness. Google was famous for having a big slide. There were companies that had happy hours and fitness classes on site. And that was really in the name of making people feel like they could just have their whole lives take place at the office. When you think about who that type of work style best serves, of course it's going to be people who don't have child care responsibilities. So that system was still set up to best serve men.
