As an American I'd absolutely say Idiocracy, but that's just my little corner of humanity.

Wall-E by way of 1984.

Contagion and Children of Men - while they didn't look far into the future and dealt with existing problems, it's still horrifyingly accurate.

Idiocracy/Dont look up/1984/Judge Dredd

You better start believing in cyberpunk dystopia, Miss Turner. You're in one!

Not sure which one. But we already pretty much check all the boxes of cyberpunk.

100% its cyberpunk. corpo takeover with having to use technology to get by even when it is bad for you.

Idiocracy.

Birth rates are down everywhere and the majority of the people left making lots of babies are not the ones you wish would be having them. Being virtuous and on the "right side of history" means nothing if those values die with you and are not passed to the next generation.

Idiocracy but mixed with the Neuromancer series and 1984.

WALL-E. We just don't have a way to escape yet, but the rest is happening regardless.

V for Vendetta

A combination of Snow Crash and Idiocracy

100% no doubt The parable of the sower and subsequent book. I read that book - started reading it - in June this year and read it over about a month. It was very creepy to be reading a sci fy book set in the future that is now my present and while it is not as bad right now as Octavia Butler makes it out to be, we are definitely heading there if drastic action is not taken immediately.

Edit: the books in order: (Only two, sadly she died while writing the third but still both worth reading, there isn't a clif hanger at the end) https://www.octaviabutler.com/parableseries

Lots of good suggestions so far, Brave New World and Don't Look Up would be right up there for me. But my #1 is this...

The Machine Stops (PDF) Written in 1909 so out of copyright, this book is so ahead of its time it makes remarkable reading today. The amount of things predicted that describe the modern day is incredible. It's also not that long, so well worth a read.

Her.

I do believe that a lot of aspects of The Ministry for the Future by K.S. Robinson have chances of becoming true.

The deadly heatwave in south Asia, governments going rogue and playing with geo engineering on their own, climate refugee camps and the general sense of too little too late.

But the book is fairly optimistic, so hopefully, people of the world getting together and accepting a new paradigm will come to be true.

I could see the Golgafrinchan telephone sanitizer situation coming to pass.

Horizon Zero Dawn: Total extinction by the 2060s because some mad, narcissistic Elon Musk guy overestimates himself and fucks it up for the whole world? Doesn't sound too far-fetched to me right now.

The Water Knife by Paolo Baccigalupi is pretty on the nose for the near future of the southern US

1984

Parable of the Sower

It was written as near future fiction anyway. In fact the dates mentioned in the book start out in our past. Just the catalyst events haven’t quite happened yet. Add a few years to the dates and I could see us heading towards that kind of societal break down.

Brave New World

We’re already living it

Been reading Corey Doctorow lately and catch myself thinking, "Aw c'mon! That's not how it works!" And then remember, he's writing about the near future.

I'm going to go obscure here and say that the world of 2077 from the television show Continuum

It ran for a few seasons; I enjoyed it for the most part. Not the best, not the worst. But definitely in terms of the premise where Corporations have essentially bought out failing governments, leading to an advanced surveillance state, and anti-corporate terrorists, etc... etc...

Our history sounds shockingly similar to Animal Farm.

Revolt against the Ottoman colonizers

The Hashemite dynasty rules the Hejaz for 10 years

Get invaded by the Saud dynasty, an ultraconservative, wahhabist group

Become an absolute monarch, where criticism = death by beheading

Pretend how it's great here, and how nothing ever goes wrong here

Destroy history of our past

Become a lifeless country, where all our work and natural resources are reserved for the Sauds

By islamic law, we are all equal. But some of us, are more equal than others.

Next step, is probably to centralize all power to MBS, which he partially already did.

Dune.

Not the cool parts, the Butlerian Jihad.

I'd have gone with WH40Ks war with the men of iron but there's absolutely no chance we reach golden age of technology levels before we fuck ourselves.
