I've read it, and I tend to think the position it argues for is likely correct, but for complex systems that we don't have models for, the only basis we have for believing it is that we have enough holes in our knowledge of how things interact that it is possible that no esoteric physics play a role and so assuming that they do not is the simplest plausible assumption. There is a good reason for that to be a working assumption.

Until we can work out all the relevant implications of mundane physics and either find them adequate or not to model he phenomena of concern, we can't say that the physics of those phenomena are known (or say that they aren't; we’re in the realm of potential unknown unknowns.)
