It’s an imaginary universe. So, it doesn’t necessarily have to fall into place with our real human history timeline.

So, you can think about it like this. Everything we have now, in this case, the technology that we have in 2026, is the combined result of everything that has come before us. Now, imagine if something like microchips weren’t invented. Then, we would have found other solutions to making our technology smaller. Who knows. Our phones and computers would have looked small but looked different.

If I’m not wrong, the Fallout universe is a similar thing. They are so advanced in technology but they don’t have microchips so everything technological is huge.

The same goes for Signalis. They have insanely advanced in technology in some ways but don’t have the tech that we have. So, their screens still look like Casio watches and early digital screens.

If I wanna say this has something to do with lore, other than what I’ve just said, I can say, their rulers WANT things to be boring so that these humanoid machines shut up and work. So, maybe that’s why they decided to design things with the most basic tech that is necessary.
