Stephen Wolfram's blog post on spacetime has sparked debate regarding his approach to modeling physics, particularly his reliance on concepts like spin networks and cellular automata. Critics, including John Conway, argue that Wolfram's deterministic framework contradicts the non-deterministic nature of quantum mechanics, suggesting that his ideas may lack a solid foundation in established physics. Some participants in the discussion appreciate the need for innovative thinking in scientific research, while others question whether Wolfram's prominence influences the reception of his ideas. There is also skepticism about the validity of his previous work, particularly his book "A New Kind of Science," which did not achieve its ambitious goals. Overall, the conversation reflects a mix of intrigue and caution regarding Wolfram's theories on spacetime.

Is anyone here into Causal set theory? This artificially looks to be like that sort of thing.

To me "silly" is like "simple" as a criteria for likeliness. Without a rigorous definition (which neither have), one cannot use it as a reliable predictor of eventual success or failure.

Silly and simple are context specific, and there are often cultural and other subjective aspects in the assessments.
