Well, I'm about to become 50, (divorced single dad) - and since late last year, I've dated several ladies breaking my near10yr celibacy.
I dated mostly around my age, or few yrs younger around 43-48 yr olds. (Currently dating/early relationship with a 38 yo, and actually feeling a bit of generation gap. lol)
During my encounters with older single/divorced ladies w no kids - I actually learned their lonesomeness is quite real, and I felt sorry for them.
Every one of them, they all brought up them about feeling alone in the world having no child, especially when they are past 45 or so - that they know they are almost certain not being able to have a child, some going through menopause.
Some were afraid of trying, some given up with a big sigh. Not exactly of regret they all said - but it did sound to me like regrets. However, vast majority of them just got so comfortable with being themselves, that there was nothing I could offer, nor I felt needed in their lives - certainly true when two adults who have spent almost 50 yrs as total strangers trying to meet in the middle can be challenging.
I also dated a couple of single moms with kid(s) - we just ended up talking about our kids most of the time, which actually ended up with no romantic spark... and some I felt like they just want a side piece, a puzzle piece to fit in their lives.
As people marry less and less, and not having kids in most developed countries... kids seem to be "burden" than "blessing" to most people who haven't had them.
Places like South Korea - their birth rate is like 0.7 (Seoul is like 0.5) - literally half of Japan (normally around 1.3 or 1.4)... and while it's true that single life can be fulfilling on its own, societal devastation (especially economical devastation) in just 20-30 yrs of that kind of population loss, I can't even imagine. Perhaps AI and automation will save them?
But what do we actually live for... is another question. Kinda sad to just to think to live day by day, making money, killing time doing whatever you like to do at the moment till one's own death sounds so meaningless.
However, I've first hand witnessed/experienced how current family/divorce law can be so devastating to many ordinary men, I am doubtful if I would marry again myself. Not because of not believing in marriage but the potential downfall/breakup was so devastating on both emotional/financial side. (Hence, I'm not a supporter of no-fault divorce at this point.)
So I see how this lady is feeling, and for certain period of my time after divorce - I did pretty similar - just did things I liked, lived on day by day, and taking care of my child, recovering and gathering my composure.
But she's still young (if she's indeed 29). Perhaps this (in)famous video will lead her to a good man, if she's willing? It's her life after all, and maybe when she's 45+.. then her generation may be entirely different from my own and she may still hold the same thoughts as she does now? I think that's sad thing, but she doesn't need my sympathy nor my criticism. What worries me though, is that this may not be all that uncommon among young folks and where it will lead our society. Realistically, I only have 20-30 yrs to go, and would love to see the society more burgeoning and happier place, than all so fear driven and divided when I kick the bucket.
