I think especially online there's a lot of emphasis on "everything is wrong". A mission like this is hard to ignore and highlights the bias. On the whole, despite setbacks, we continue.
There's a lot of money/hay/political power/etc to be made from "everything is wrong" - it's hard for "good news" to really get into your bones.
Not to say it's the best of times, nor to say it's the worst of times, mind you. Just that it's really hard to objectively compare.
If you want to dispel a bit more of the ever-pervasive online pessimism bias, read up on global rates of hunger the last time we flew to the moon (1972) vs now. The reality is, for all the problems we face today, there's no sane answer other than today to the question "when would you prefer to be born as a random person on earth"
