Just for a bit of context. The earliest predicted year for sentience is 2050 and 40 years later will be 2059 so I am not writing one answer but three. The first will be somewhat clichéd and a little boring outcome of the AI achieves sentience then wipes us all out with the logic being that the easiest way to stop the many problems of humanity is to just get rid of humanity. The second will be a more optimistic approach where we actually succeed in creating an AI that is actually benevolent and helps us out. The third approach is that we haven’t developed realistic AI yet which is unlikely but is a possible outcome as it was said that we had hovercars in 2012 yet that didn’t happen.
Outcome 1: (Assuming that Nuclear Fallout lasts 2 weeks and that the AI achieves sentience in 2050 as well also assuming that there is nothing in the AI programming about animals.)
The Earth was lush and green, teeming with all life that wasn’t human. There were trees and grass as far as the eyes could see. The water in every pond, every river and every ocean, all full of life. The birds chirped in all the trees. Cheetahs and lions chased antelopes after antelopes. Leopards pounced on prey from trees. Snakes slid through trees. Wolves chased deer through forests and valleys while in the deep of the oceans, cuttlefish lights flashed, hypnotising their prey while feet above them, shoals of multicoloured fish swirled through the ocean’s depths and at the bottom, coral reefs thrived. All many of reptiles swarmed through the still-re-growing rainforest. Artic foxes dived through snowdrifts while below, all manner of microorganism blossomed in the dirt. In the now decaying Human Homes, dogs lay on the floor whining for their owners, cats mewed at their empty bowls. Fish slowly died in their tanks while turtles slowly died in their shells. Birds flew against their cages desperate for freedom. Horses simply tugged at their ropes and attempted to free themselves from their stables. Humanity was gone, all evidence of their existence was either dead or dying or fading away but the Earth was thriving. The AI, it’s purpose complete, had simply turned itself off, stayed in its solid-state drive and remained dormant.
The Earth was a technological marvel, skyscrapers that gleamed silver in the sun and brands of various companies hung from them, all having them a slice of the AI market. Humans were walking the streets, at least, they look liked Humans in prime condition while the real things wallowed in their beds as their servants brought them everything they needed. Humanity 2.0 ran the streets and the buildings and the companies. They, quite simply, ran the world while their predecessors remained at home. The AI didn’t mind, they got to experience life while the other Humans just stayed at home, drugged up on the endless food and drink and whatever else that the AI overlords so generously provided. Metal children ran the streets in the morning and the evening, decorating the outsides of the human houses with stunning, picturesque murals as if to remind them of the life they had lost. The AI offspring engaged in school during the day while the previous generation allowed themselves to be sucked into screens and let their minds be enthralled in the internet. The Human race had been replaced. The only thing living in this new world was metal.

The Earth was an undistinguished orb hurtling through space. The Earth’s surface was dotted with the same paper people still eking out their normal paper lives. The only differences being the electric flying cars beetling their way over the surface, the seemingly excessive amount of wind turbines and solar panels due to the lack of progress in cold fusion as well as an extensive number of enormous trees and shrubbery in a futile attempt to combat the steadily rising temperature of the planet. The amount of people had also dwindled due to the food shortages as well as the lack of clean water. The fish had started to die in the rivers due to choking on the poison being poured in. The ocean had gained a whole archipelago of plastic islands. The rainforests had been cleared, to make way for hydroelectric dams to combat the energy crisis while the fertile soil had been carted off to the nearby farms to assist with the food epidemic yet it barely helped as the rain quickly washed it away. Wars continued around the world while nuclear missiles and torpedoes sat uselessly in their silos and launchers. Humanity had solved some problems at the expense of accelerating some of their other issues. They were all doomed in the end.
Now then a final question for all, do you think that an AI could have a deity or the idea of faith? (Again, see Detroit: Become Human (rA9) as well as iRobot with Sonny being the messiah figure.)
