I liked the exit mundi story about our crops becoming too homogeneous to properly nourish the food chain or something like that so we go starve to death.

assuming we don't get off the planet first, probably advanced biological warfare or something similar.

https://en.wikipedia.org/wiki/Timeline_of_the_far_future#Future_of_humanity

100,000 years from now - Earth will likely have undergone a supervolcanic eruption large enough to erupt 400 km3 of magma. For comparison, Lake Erie is 484 km3.[18]

300,000 years from now - At some point in the next "several" hundred thousand years, the Wolf-Rayet star WR 104 is expected to explode in a supernova. It has been suggested that it may produce a gamma ray burst that could pose a threat to life on Earth should its poles be aligned 12 or lower towards Earth. The star's axis of rotation has yet to be determined with certainty.[22]

500,000 years from now - Earth will likely have been hit by an asteroid of roughly 1 km in diameter, assuming it cannot be averted.[23]

1 million years from now - Earth will likely have undergone a supervolcanic eruption large enough to erupt 3,200 km3 of magma, an event comparable to the Toba supereruption 75,000 years ago.[18]

100 million years from now - Earth will likely have been hit by an asteroid comparable in size to the one that triggered the KPg extinction 66 million years ago, assuming it cannot be averted.[45]

500-600 million years from now - Estimated time until a gamma ray burst, or massive, hyperenergetic supernova, occurs within 6,500 light-years of Earth; close enough for its rays to affect Earth's ozone layer and potentially trigger a mass extinction, assuming the hypothesis is correct that a previous such explosion triggered the OrdovicianSilurian extinction event. However, the supernova would have to be precisely oriented relative to Earth to have any negative effect.[52]

600 million years from now - The Sun's increasing luminosity begins to disrupt the carbonatesilicate cycle; higher luminosity increases weathering of surface rocks, which traps carbon dioxide in the ground as carbonate. As water evaporates from the Earth's surface, rocks harden, causing plate tectonics to slow and eventually stop. Without volcanoes to recycle carbon into the Earth's atmosphere, carbon dioxide levels begin to fall.[54] By this time, carbon dioxide levels will fall to the point at which C3 photosynthesis is no longer possible. All plants that utilize C3 photosynthesis (~99 percent of present-day species) will die.[55]

800 million years from now - Carbon dioxide levels fall to the point at which C4 photosynthesis is no longer possible.[55] Free oxygen and ozone disappear from the atmosphere. Multicellular life dies out.[56]

1 billion years from now - The Sun's luminosity has increased by 10 percent, causing Earth's surface temperatures to reach an average of ~320 K (47 C, 116 F). The atmosphere will become a "moist greenhouse", resulting in a runaway evaporation of the oceans.[57] Pockets of water may still be present at the poles, allowing abodes for simple life.[58][59]

1.3 billion years from now - Eukaryotic life dies out due to carbon dioxide starvation. Only prokaryotes remain.[56]

2.3 billion years from now - The Earth's outer core freezes, if the inner core continues to grow at its current rate of 1 mm per year.[61][62] Without its liquid outer core, the Earth's magnetic field shuts down,[63] and charged particles emanating from the Sun gradually deplete the atmosphere.[64]

Either nuclear war, probably as a result of the effects of climate change
Or AI . . . possibly just swarmbots controlled by bad actors, this may not make us extinct but it will end human innovation and plunge society into insurmountable darkness.

Some say the world will end in fire,
Some say in ice.
From what Ive tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.

The more I think about it, the more obvious it is that humanity isn't set for long term survival.
We don't have any 100 year, let alone 1000 year projects.
Instead of taking any precautions against nuke, we've kept building up instead of into the Earth, guarding against disaster man-made and natural alike.
Most people can't survive a month in case of emergency, without going to the grocery story.
We have "plans" but no actual purpose built hardware in case we need to deflect an asteroid.
We're breeding superbugs with our misuse and overuse of antibiotics. We still* have idiots stopping their prescriptions early against all warnings.
Drone and killbot swarm technology seems inevitable, this will be a paradigm shift in the way we war, police, and simply live.

We are absolutely fucked.

I think we're fragile right NOW, but who knows how big technological and medical progress we might come up in next 100 year, or even next 1000 years. Just look how huge progress happened from 1930's to 2018.
