This is exactly right - I've had my kids in my mid 30s, and while there are upsides, there are downsides.
At a friend's wedding, his great grandmother was there. Hearing that, I realised there is an amazing upside to having kids a little earlier.

Think of the advantage of having kids later: Your kids get to be born into a deeper and better future, and may some day enter the 22nd century, lucid and able.
But live for yourself and what you think is good. It's always a tradeoff. Having your grandparents at your wedding is nice, sure, but you can't optimize for everything.
I know this is an extreme example but, talk about downsides!
One of my great grandmothers was in an actual arranged marriage at age 14 to a man who was like 60 years old. She managed to get out of that one, but had to marry another man (my great grandfather, who I never met) to do it.
It was a different world back then, but compressing generations to the point where you are able to know your great grandparents usually requires some creative accounting that wouldn't fly for most people today.
My point is that multiple generations of people need to have children at very young ages - often under conditions where they lack agency - for you to know your great-grandparents. It was a great experience for me, but every generation before me had a hard life.
