I think the interface of LLM with formalized languages is really the future. Because here you can formally verify every statement and deal with hallucinations.

If this were the case, I don't see why we'd need to wait for an AI company to make a breakthrough in math research. The key issue instead is how to encode 'real-life' statements in a formal language - which to me seems like a ludicrous problem, just complete magical thinking.

For example, how might an arbitrary statement like "Scholars believe that professional competence of a teacher is a prerequisite for improving the quality of the educational process in preschools" be put in a lean-like language? What about "The theoretical basis of the October Revolution lay in a development of Marxism, but this development occurred through three successive rounds of theoretical debate"?

Or have I totally misunderstood what people mean when they say that developments in automatic theorem proving will solve LLM's hallucination problem?

Probabilistic reasoning is possible in a formal setting; It produces a probability distribution over answers. To ground probabilistic logic itself I'm not aware of much progress beyond the initial idea of logical induction[0].

This takes for granted a formal setting, which is what I'm questioning in any of these 'real world' contexts.

A formal model of semantics would likely be a low-level physical representation of possible states augmented with sound definitions of higher-level concepts and objects. I don't think humans are capable of developing a formal semantics that would work for your sentences (it's taken us hundreds of years to approach formalization of particle physics), but I think that an automated prover with access to physical experiments and an LLM could probably start building a more comprehensive semantics.
