It was inspired by many things. I wouldn't be surprised if this is one of them, but it's not the only inspiration.

It's inspired by the manga "BLAME!".

From Wikipedia:

"Blame! is set in what is simply known as "The City", a gigantic megastructure now occupying much of what used to be the Solar System. Its exact size is unknown, but Tsutomu Nihei suggested its diameter to be at least that of Jupiter's orbit, or about 1.6 billion kilometers. In the manga, this is also suggested by Killy crossing an empty, spherical room roughly the size of Jupiter, suggesting that the planet had been there but was disassembled as the City grew.

As revealed in the prequel NOiSE, the City began as a much smaller structure on Earth, created by humans with the aid of the robotic "Builders". Humanity controlled the Builders through the Netsphere, a hyper-developed version of the Internet accessible only to those with an identificatory genetic marker known as the Net Terminal Gene. Any humans without the gene who attempted to access the Netsphere were exterminated by a special task force known as the Safeguards. Eventually however, a terrorist cult known as "the Order" released a virus that made all humans lose their Net Terminal Genes, thus cutting off their access to the Netsphere and their control over the Builders. Without specific instructions, the Builders began to build chaotically and indefinitely, while the Safeguards' programming degraded into killing all humans without the Net Terminal Gene whether they wanted to access the Netsphere or not.

By the time of the events of the manga, the City has basically become a series of layered, concentric Dyson spheres filled with haphazard architecture, largely devoid of life. These layers compose the supporting scaffold of the City, known as the Megastructure. The Megastructure is extremely durable, with only a direct blast from a Gravitational Beam Emitter being able to drill through it. In addition, the underside of each Megastructure layer periodically illuminates the overside of the one below to provide a day–night cycle. Traveling between layers is generally challenging due to the City's chaotic layout and the dangerous Safeguard response such endeavor may cause, with the means to do so being either climbing stairs for days or taking elevators that reach relativistic speeds. The buildings on each layer are largely uninhabited, although scattered human tribes, rogue Builders, hostile Safeguards, and Silicon Life can be found throughout the entire City. "

As I was reading this I was like "yep...sounds about right" lol.

Liminal spaces before spaces were considered liminal
