@Sara_Imari These are very topical issues atm especially AI & the dangers it presents given its biased programing. It would be worth checking out the latest book by Biologist Jeremy Griffith for a denial free & truthful account. Totally clarifying @World_Transform

It's funny listening to talking monkeys muse about the origin of life. The universe is super intelligent and hyperdimensional... yet science calls life "randomly emerging." 😹😹😹 The only honest answer to the origin of life is "We have no idea." I love the theoretical thinking here though, very entertaining trying to wrap our minds around this.

Here's my conversation with Ivanka Trump, a businesswoman, real estate developer, and former senior advisor to the President of the United States. We talk about politics, architecture, philosophy, fashion, music, parenting, martial arts, and much more. I've gotten to know Ivanka well over the past 2 years. We first connected over our mutual love of reading and discussing books (for example by Marcus Aurelius, Joseph Campbell, Alan Watts, etc). She is a truly kind, compassionate, and thoughtful human being, and I'm honored to be able to call her a friend. It's here on X in full, and is up on YouTube, Spotify, and everywhere else.
