Thoughts on the "Mathematical Universe" Tegmark

I read the "mathematical universe" of Tegmarka. And immediately his judgments in the spirit are striking: "Economics is a kind of political prostitution," "metaphysics is something frivolous."

Yes, it is possible that many (perhaps most) economists are political prostitutes, metaphysics are just freaks, businessmen crooks. But from the fact that most economists, metaphysicists and businessmen do not yet follow that economics are political prostitution, metaphysicik A - nonsense nonsense, and business is scam.

Ultimately, Tegmark begins his book with a quote from Plato and, it seems that a significant part of it is engaged in what can be called metaphysics and natural philosophy. That is, following his own expressions, something frivolous. But his book, according to his recognition, is a presentation of his scientific biography.

Is it not worth the Tegmark with such a perception of philosophy to consider all his life to something frivolous?
