David Deutsch is an awesome thinker. His day job is that of a physicist involved in cosmology and quantum physics. He is considered the “father of quantum computing.” Quantum mechanics is far above my IQ level; I couldn’t possibly understand it. Quantum computation too is beyond my reach.
Deutsch is a genuine genius. What was previously called the “Church-Turing thesis” is now called “Church-Turing-Deutsch thesis.”[1]
Deutsch is a proponent of the “many-world interpretation” of QM proposed by Hugh Everett. For an accessible introduction to MWI I recommend the article on “Many-Worlds Interpretation of Quantum Mechanics” in the Stanford Encyclopedia of Philosophy.
Being a physicist is Deutsch’s day job, as I mentioned before. He moonlights as a deep thinker on other important matters. In an interview on economist Tyler Cowen’s podcast, Tyler characterized Deutsch as the first and only “philosopher of freedom.” I will provide a link to it later.
