It is barely at the level of an undergraduate essay on AI (or AGI or ANI, as the author prefers). A hand-waving argument about "computers not being in the world" that relies on not bothering to define "computers", "being in" or "the world". Convenient avoidance of almost every more subtle anti-Searle/anti-Dreyfus critic (notably Dennett). Almost wilfull narrowing of a much broader argument about the nature of reality and the connection between causality and conventional parametric science, when these things lie at the heart of the author's argument (such as it is).
It is amazing that Nature chose to publish this.
