You'll find lots of people saying Diamond has been "debunked" but by that they mean "here's some criticism someone posted online". It's a remarkable work of analysis tracing the causes of human progress over thousands of years.
Fukuyama is a real realist. What I mean by that is that he doesn't deny that progress has occurred (something some people believe), but he points out how precarious that progress is and that it can go away (something some people deny).
I don't understand why it's a controversial statement to say that progress isn't inevitable and that decay can sometimes happen, but for some reason it is. I think his books, among many other things, are useful for grasping that progress takes hard work and can, like anything in this world, be ruined by laziness, corruption, or simple accidental misfortune.
Both were turned into TV miniseries by the BBC (plus a successor to Connections that I haven't seen).
I'd like to add the fiction Foundation series, by Isaac Asimov. Although they began being published in 1942 and Asimov got some technology wrong, it's a must read.
Also work by Stanislaw Lem. My favourite one is The star diaries, and it mixes pure sci-fi plot with a lot of philosophic thoughts about the future of human progress.

The Measure of the World by Denis Guedj
There is an excerpt here:

The matter is interesting and IMHO very well told, as besides describing the peregrinations of the scientists it gives an insight into the period, the science revolution and Enlightenment.
One of the most enlightening reads out there. Read both Why Nations Fail and Guns, Germs and Steel.
It is a good read on how information has changed humanity and is still doing so.
It's what happens with the human race if the moon crashes into the Earth.
