I have thought of the same thing in the domain of neural nets. You want to understand an image? Build a graph of the objects and their relations. You want to understand a text? Turn it into a graph. Need to simulate the environment? You can represent it as a graph. Want to mine a huge database of common facts? Represent it as a graph (database of triplets subject-relation-object). Even the execution of a program could be better conceptualised as a graph.
Graphs seem like an universal format. Graph Neural Nets have been a blooming subfield lately, ever since Thomas Kipf's paper [1] which in three years has accumulated over 2300 citations.
The main difference between classical neural nets and GNNs is that GNNs have permutation invariance. You can rename the nodes of the graph and still have the same graph.
Previously neural nets only had translation invariance (CNN) and time invariance (RNNs). Graphs would solve the combinatorial explosion by virtue of their permutation invariance - a problem which limits previous models of neural nets. Instead of learning all possible combinations of input objects you learn the pairwise relations, then you can generalise those relations to new configurations.
On a side note, the insanely popular transformer architecture (based on soft attention) is a kind of implicit graph, where the connectivity is evaluated based on the dot product similarity of the key and query objects.

Compression, folding, encoding, and other information theory ideas have analogues represented as these, and the bottom up/depth first search of the problem space seems to come at it from the wrong direction.
We're well into indulging Internet crank territory here but I'm naively speculating that for every known theorem, there is a consistent object/morphism representation of it, and the rules we're getting good at finding for these relationships (graphs) will yield insights we were missing for lack of an encompassing consistent abstraction.
But given the failure (of adoption) of dataflow programming languages I don't think there will really be that much of a jump in understanding just by visualizing stuff as graphs.
What are some alternatives to graphs? Well some kind of language, say a programming language. But underlying any program written in any programming language is a graph of the parts of the program and their connections to each other. For instance a variable may be written in one section of the code and read in another, and if it is the same variable then those locations in code are part of the graph showing the data-flow of the program.
So it is my intuition too that graphs are the fundamental representation of reality as we see it, the parts of reality and the connections and relations between those parts.
Knowledge is knowledge about containers and parts and how those related to each other. We can describe it in natural language or perhaps in algebra but really the picture we are expressing in any language is that of wholes and parts and their connections.
This is my intuition about it I don't know if such a general intuition is much good in actual theory formation. Theories are graphs I think.

that's not literature, that's bad grammar.
Sorry.
Lambda calculus is partially fun just because of the minimal extent of its description.
Edit: well, an easy find, https://esolangs.org/wiki/Lambda_Calculus_to_Brainfuck

simply speaking, bf can implement lc, and vice versa, which would proof the claim.
Edit: the ugly bit is that IO is always an ugly hack and potentially makes the program indetermined and thus impossible to proof a priory. but one can probably prove that they are equivalently unprovable.
Do you mean turing complete?
It looks quite different and I wonder which one is better? Or are they the same really?
