I'm very pessimistic, so I tend to think that we're _already_ existing within the constraints of the dystopian cyberpunk apocalyptic future. It's just that we, as humans, cannot perceive the apparent movement of celestial bodies (if we try to actively notice how Moon "walks" throughout the skies, she'll seem pretty still, yet the Earth is spinning and her position will change in relation to us). It's easy for us to look at the past, through the lens of history books, and notice the boundaries between Æons, but people experiencing specific moments (e.g. the two World Wars) couldn't perceive it until it was finally announced and/or became part of a history book after lots of consensus between historians and archivists. We're probably in the mid of a WWIII, yet humans can't perceive it until it becomes the footnote of a future history book (if there's any future to tell about the past).
How do you think it'll be?
When life imitates art, it does so in a pretty boring fashion. It's easy for us to think of a machine dominance through the lens of a Terminator franchise. Although we're, to some extent, being "dominated by machines", the real-life Skynet is quite boring. It doesn't involve fancy time travel and red-eyed robots with automatic machine guns chasing John Connor, it's beyond the level of absurdity no artist could think of: society is being dominated by dumb autocomplete algorithms which outputs recommendations of a daily consumption of rocks alongside with the usage of glue to stick cheese to the pizza.
Drought, famine, deforestation, broken down concrete buildings as far as the eyes can see; toxic air, toxic water, a steep decline in population growth, few animals, and even fewer birds.
Speaking about birds, it broke my heart when I saw an article stating how coot birds are naively using plastics and other human wastes to build nests... because humans are increasingly polluting habitats, and this is reshaping (in a very dangerous way) how animals behave.
Air will be sold
While late-stage capitalism can indeed find ways to monopolize the air we breathe, I doubt they can go further with it when the entire biosphere finally disrupts and the planet enters an Anthropocentric Hadean Age, with both boiling and freezing temperatures becoming the daily, new _de-facto_ normal around the globe. They _could_ manufacture oxygen through water electrolysis, but they can't manufacture the entire Terrarium life needs to survive the harshness of a vast, indifferent Cosmos.
In the end, they'll try to run to another (exo)planet (just like the "Don't Look Up" plot), leaving behind the populace (those who couldn't even dream of affording space travel, 99.9% of world's population) to a hellish world.
The most dangerous predator one can encounter - man. People will dread meeting someone else more than any bird or beast.
To some extent, since _Homo sapiens_ discovered the fire, _Homo homini lupus est_.
The only goal of life; the only ambition - survive.
Sometimes, it's the opposite: when faced with the futility and absurdity of human existence, cosmic nihilism is the logic outcome for some who stop to think deeply about their current, mundane difficulties. Suddenly, even surviving loses its purpose. What was feared before, the ominous touch of the Lady Reaper, becomes part of the worldview, or even desirable as the goal to be achieved, even though there's still a survival instinct making this goal quite difficult by active means. Actually, I'm kind of describing myself here: oh, how I simultaneously fear and desire Her touch... How I fear and desire being held captive by Her claws and trapped to a flight under Her majestic dark wings through the fabric of spacetime continuum, towards the boundaries of a cosmic non-existence, from where I was pulled when I was born... Back to home, in a sense...
I'm still compelled to "seek survival" by this biological automaton I call "body", yet my mind can't help but think of my real home, the nothingness.
