Wolfram's Physics Project is a very interesting one and its recent evolution fascinates me. I think that the recent discovery of the ruliad is a good progress in the project. However, there is something I don't understand:

According to Wolfram's writing about the ruliad (https://writings.stephenwolfram.com/2021/11/the-concept-of-the-ruliad/), there is only one ruliad which contains all possible formal systems. I understand why there should be only one ruliad as it would contain all possible computational rules by definition. However, I can imagine a formal system or abstract situation where somehow there could be multiple rulial spaces or "ruliads". So, at the end, wouldn't it be possible that there could be other ruliads (for computational systems, I'm not talking about other possible "ruliads" containing hypercomputation)?
