  • Love the podcast

    Hey Lex and team, love the podcast! I love the diverse topics and it's always interesting to learn something new from your guests. I especially love Physics related episodes as well as tech/science. I wanted to ask: Do you plan on bringing video podcasts to apple in the near future?

  • Really good info but really long.

    I agree the podcast has some really interesting stuff but you can’t take 17 minutes to go through your sponsors and ramble on that’s just filler. I don’t know how podcast became that way but it’s kind of goofy when you have to sit through 17 minutes of rambling. It’s like waiting at a doctor’s office.
