I had my first at 32, and that was earlier than my friends. And when I pick mine up at daycare, I feel like I am the youngest. But I also do not feel noticeably worse off physically in mid 30s compared to mid 20s.
I disagree that there will never be a better situation. A couple with secure cash flows and in demand talents can optimize when they have kids to accommodate goals (for example, their preferred living situation, career goals, etc).
Things like moving, and working strenuous roles while having kids seems less than ideal. Of course, if you want 5 kids then waiting is not an option, but if you want 2, then there is some room for maneuvering.
