Some of these arise from of Gerard O’Neill work on space colonies. I saw these in National Geographic in the late 70s they were hugely inspirational to me. Note while Musk advocates settling Mars Bezos has indicated a preference for space colonies such as O’Neills. https://en.m.wikipedia.org/wiki/O%27Neill_cylinder
None of these Arks are going to support billions.

I think that is why Nasa's Havoc mission is maybe the best idea yet... https://www.youtube.com/watch?v=g-vK9pqonAE You still have to maintain the floating city like you would an orbital one, but you get the extra added benefits... Venus makes the most sense to me... You get the benefit of gravity similar to earth, 70~ deg f temp and gases that allow you to maintain pressure and possibly harvest for fuel...
I've been trying to figure out how effective solar power would be at the height you'd put a floating city. You're closer to the sun than Earth, much higher than Earth's surface, but in a very dense atmosphere...
We are so driven by settling other planets, which of course I think we should do, that we forget that space habitats might be a more economical and also healthier first step into space. Apart from the ones depicted in these images I'm more in favour with starting with cheaper techniques where we could wire up an initial station to a wire/tether, and put a weight (or another small station) at the other end, have them…
From what I understand, a structure needs to be quite massive to get meaningful gravity from a rotating hull unless you attempt to approach ludicrously unsafe angular velocity which would make repair / docking a big challenge. In The Expanse , Ceres station was spun up over many, many years and still only achieved about 1/3G. Not to use a fictional universe as a basis for science but afaik they at least tried to do t…
The reason it has to be so massive is that otherwise the difference in the G-forces between your head and your feet can make you sick[1].

There’s an under appreciated problem with spinning space stations: they would be set off balance by uneven distribution of weight around the ring. This would make small scale rings a bit problematic because people and stuff need to move around. Rings the size of halo would have enough mass that the movement of people wouldn’t be enough to matter.
In the book/TV series "The Expanse", they actually spin up massive asteroids and live inside tunnels, effectively like a ring but made of rock, to offset the fact that it doesn't have enough gravity otherwise. Neat concept, although will likely end in failure.

You mean retro Elisyum maybe :) Also, how did we get from this cool stuff to zombie apocalypse, dystopian society and barren wastelands in our sci-fi?

I love the expanse, such an amazing series of books
