  • Well made, long and thought out.

    The only bad thing about current day lex is waiting for a a podcast is like waiting for Christmas and yes I know it’s quality over quantity and he’s doing his own thing with his robotic engineering stuff which I will admit that’s a very good reason, but do I miss the days with tons of interviews to watch.
