I think the first to go all in on "reality is made of information" was Konrad Zuze, whose Rechnender Raum is a psychedelic read. Interesting even though I don't think there is much reality in the information it provides.
Seems to be a losing battle to make people understand that Wheeler's "It from Bit" does not mean "reality is made of information" (it was about defending an epistemic view of quantum mechanics, where the wave function isn't real, only measurement outcomes are), and likewise...

We feel that we understand things when certain patterns of explanations are in place. If reality doesn't follow those patterns, our understanding suffers. On to the third such eureka fallacy I've blogged about: explanation by optimization.
