Friston was also on Sean Carroll’s podcast recently—link. I found it slightly helpful. I may listen to this one too; if I do I’ll comment on how they compare.
Update: They’re complementary. The Sean Carroll podcast had much more technical details, beyond what even I could follow (as a professional physicist). The Lex one is much more basic. In the Lex one, I think Friston was better at clarifying which parts of his free energy stuff are weird galaxy-brain ways to think about obvious tautological things, and which parts are content-ful falsifiable hypotheses.
