Abstract
In this note I comment on the article ``Consequences of Undecidability in Physics on the Theory of Everything'' by Faizal-Krauss-Shabir-Marino (FKSM). I first summarise what I take to be the central claims and contributions of the work, and then highlight why it is, in my view, a genuinely important step in the dialogue between mathematical logic and fundamental physics. I finally suggest a clarification concerning the status of non-algorithmic understanding in their framework, in order to avoid any appearance of human-centrism, and point out that their picture naturally invites an interpretation in which a consciousness-like, non-algorithmic form of understanding operates in a Platonic realm that generates the informational ``bit'' and, through it, the physical ``it''.
