Repost from the discord to maybe get some more feedback and theories. Lots of spoilers in this ofc
My theory is the world of motorslice is some kind of layered superstructure, just like an onion, due to the ending of the game. We go into the artificial sky, and we arrive near yet another megastructure, plus P saying that being a slicer is a never ending job that is worse than death. Now an array megastructure could either hint at the structure we play in being multi leveled, or it could mean, if my theory is correct, that she found one that leads further up, into yet another megastructure. By an alphastructure I assume she means a very old structure, so judging by how far humanity has fallen compared to what is assumable it achieved in the times before the game, I would further theorise that these are structures that could instantly lead upwards, without needing to constantly search for and go through other megastructures, maybe even with no or minimal motors. This would also explain how in the game the weather is very dry and desert like, and after we get to another layer it completely changes, meaning that each layer could have it's own climate and weather effects. And also maybe this is why Orbie's connection to the HQ is lost, because they got too far away for the signals to reach them through all the layers. If my theory is correct, then perchance why slicers clear these megastructures of motors, is to later be inhabited by humanity once again, or to reach the real surface, or maybe for some other purpose, feel free to make theories about it. The pic is for better understanding, hope I actually did something here.
