I'm not particularly a pessimist or an optimist. There's some improvments in humanity as time marches on.

But there's some bad things too. Like climate breakdown is one bad thing I'm sure my kids are going to live through.

I find it completely believable that the next 30 years will include a gigantic war with nuclear. Hundreds of millions could die, everything changes.

But I also find it completely believable that that won't happen.
