Same age, same thoughts. The past was violent & sucky but it really felt like we were making progress, things were getting better. Some things have, there's a lot less violence where I live, and more to do, the city has progressed.
Honestly I think the slide started after Bush vs Gore, and very often wish I had been in the other timeline, where the votes got counted before he conceded, Gore seemed conceited but smart, geeky and took good ideas seriously.

I have kids & step kids and kids my husband previously adopted and they are intelligent in different ways. Only one had some developmental delays and is not, she struggles, the rest - 3 academic hyper achievers, quick thinking and quick at learning new things, all ended up scientists of some sort. Two who are hardworking and think they are not as smart but whenever they have to take a test they score in top 10% or so, those two ended up in military intelligence. Youngest kid still in school can see things in different ways - can find solutions or ideas none of us even think of, and though they ALSO don't think they are as smart as the others, I personally consider that to be very intelligent. One who was smart & frustrated, depressed, and no longer with us - saw too much I think but could not find hope. So different people are smart in different ways, and sometimes in ways that are not helpful to them.
If I had to choose one quality - it's humor. That ability to say just the right thing in the moment that is so funny. That quick wit is a good sign of intelligence.
