I wish all science outreach hosts interviewed their guests with as much intelligence as Lex does. He knows their work, he asks the questions that help nail what guests have to say, yet keeping it as simple as possible despite how deep and fundamental these subjects may be. Lex has a maturity that most will never get. He does not brag and put himself forward, he does not fall for the mundane and vulgar. I guess he’s got nothing to prove, he knows his stuff, he puts the work to learn outside his comfort zone. He’s the boss.
