I like how Stephen Wolfram introduces somewhat new perspectives to looking at physics, but I'm unaware of any efforts from him trying either to (a) show/prove mathematically that current theories (be it Newtonian, qm, gr) are mere emergent properties from his hypergraph cellular automaton universe and/or (b) relate any sort of experimental data to this hypothesis that goes beyond the qualitative description he gives in these talks.
I enjoy Lex, although I have been listening less over time. However, the Wolfram/fridman combination makes me envy the deaf.
How come?
I felt like Lex just took him on faith for so many points. This was a hard listen to me. Some really interesting points were raised but I didn't feel like there was much fleshing out of how certain the conclusion was not exactly how any of the conclusions were reached. Maybe I'm just not intelligent enough.
