Under the hood, Minetest is way cooler than it looks: It actually implements a generalized 3D cellular automaton framework in which each cube in the world is driven by a small Lua program – which makes it much easier to mod than Minecraft. Many people like the Minecraft-style mod, but there exists, for example, an implementation of Wireworld: https://en.wikipedia.org/wiki/Wireworld

Disclosure: I was an early Minetest contributor when you still had to provide C++ patches to add new features (2011) and drew some textures.

That doesn't seem scalable at all.

Cellular automatons scale great. What do you think the problem is?

And minecraft is stuck on a single sim thread, it can't even split of worldgen. Almost any threaded method could beat it.
