It's funny to think that no matter how our technology develops, cats will be right there along for the ride, completely ignorant of it all. It's humorously comforting to think of an interstellar civilization powered by fusion and AGI serving cats just as they're served now. Scratching posts on starships seems to be inevitable.

The domestication of cats happened because of the invention of farming.

If you store grain in a granary, it attracts a lot of insects, rodents, etc. Cats that could tolerate getting close to human settlements found a good food source. And humans like this, because the cats protect the grain without eating it. So you can see why ancient agrarian societies like the Egyptians held cats in high esteem.

And despite only having a few thousand years to adapt to each other, ends up cats and humans can understand each other and form emotional bonds pretty easily.

I imagine we'll see cats on spaceships of the future just like they were the norm on ships in the age of sail.

This seems like a book.

Humans extinct for a billion years, AGI and robots tasked to feed and "take care of the cats".

I imagine entire cities, houses built, all empty save cat and humanform robot.
