Immortality. We're on the cusp of the singularity type stuff where we can live on in some kind of AI form. If you zoom out on history it goes roughly big bang, planets form, biological life evolves and gets smart, bio life is superseded by tech evolution. We're privileged to be alive at the one time in tens of billions of years that it happens.

Plus the Pinker stuff - less war, more prosperity and so on. Things seem worse than they are because doom sells newspapers, cyberpunk novels and the like.
