Honestly, I don't. I came up in the '80s, wasn't diagnosed with autism until 2022. My life would have been so different if I had known about it when I was a child, and if autism was as well-understood as it is today so that I had the support I needed. Kids today who have issue like that are identified much earlier and helped more. The steady march of knowledge and science is almost always a good thing. So, the present and the future are always the place to be for most people most of the time. Of course a Gazan isn't feeling the giddy excitement of scientific discovery at this moment, but for the human species as a whole, things have never been better. There is always someone suffering immense, unimaginable hardship. The human project is overwhelmingly not that.
Every generation has existential concerns, too. Climate change and the rise of fascism is on the cards right now. When I was a kid and adolescent in the '80s and '90s, I was in the middle of the N. Irish 'Troubles'. Before that, people had the Cold War to worry about. Before that, WWII and WWI. But things are always better than they were 'yesterday' if you take stock of everyone as a whole and not just those suffering the worst in any given moment.
If you took the average kid born today in an average society, and transplanted them into the 1970s with the same socioeconomic starting point, it would be tantamount to gross child abuse given the vast ocean of stuff they could have had, but now will never have (in their childhood, at least). And I'm not even talking about technology and the internet; just the treatment of children by the state and schools alone would be night-and-day different. Kids are individuals today, in the '70s you were your parents' property and didn't develop a sense-of-self worth respecting until you were old enough to get drunk.
I still wouldn't bring a kid into existence, but for those that are here already, 2025 is the best time to be born. Like if I were my parents, I would not have had me while the country was tearing itself apart with bombings and shootings every day. But I'm glad I was born when I was and not when my parents were kids.
