The best podcast

I’ve listened to Lex for many years, hands down the best podcast available!

mikeyy_aus ,

Intellectual potency

Lex’s capacity for sincere curiosity and depth of thinking is rare and must be cherished. A product of being made in the USSR yet designed in the USA offers a rare potent combination of great intellectual possibility and perspectives for questioning.
