Today, I welcome Sal Khan back to the show. I met Sal for the first time when he came

on this podcast in the spring of 2021. We talked then about Khan Academy and the small experimental

school, the Khan Lab School he started. I'm excited to talk today with Sal, but his

latest ambitious endeavor, the launching of the Khan World School. The young people that

we're starting to see come through the door for the Khan World School, these are going to be

the kids who are going to change the world. Welcome to people I mostly admire with Steve Levitt.

When I launched this podcast, I dreamed that it would lead not just to interesting conversations,

but also to collaborations with my guests that might make the world a better place,

and it's actually happening. Because of that initial podcast interview,

I and my team at the University of Chicago are heavily involved in creating the curriculum

for the Khan World School. But the path to collaboration was not always smooth.

Sal, it's so great to have you back for a second appearance on the show. We've done some double

episodes where we do one interview and turn into two shows, but you are the first to make a return

visit. So I feel very honored to have you and that's fine. I'm honored to be in this spot.

Thanks for having me, Steve. Okay, so when you came on the show the first time, listeners found

your message inspirational. We received about 10 times as many listener emails as we usually get,

and most of them wanted to know how they could get their kids into the Khan Lab School. And I wasn't

surprised by that because I also wanted to get my kids into your school if you remember. And so

just a few days after the episode came out back in April 2021, I sent you an email outlining

an ambitious plan in which we, you and me, could collaborate to expand your Khan Lab School from

its current single location to 15 or 20 locations within three or four years. And I even started

assembling a team of advisors, but there was only one problem. You never wrote back to that email.
