Will they? In my little view of the world I see younger workers who use the office for a social atmosphere as the ones who want to go back. Those of us that are older with older kids/wives seem more content at home. At least that's what I'm seeing in my current company.
Long before I ever even considered starting a family, I've always preferred working from home. I very much prefer keeping my social life and my work life separate. I'm close with a few people in my industry, but only the ones I really enjoy spending time with, personally.
I also have a great deal of respect for my teammates, some of whom I've worked with on multiple projects and companies over the past decade. But I'm especially glad not to complicate our relationships beyond our work together.
