The return of BTS is a big deal. In case you were in any doubt, just look at the frenzy surrounding the South Koreans' comeback. On Saturday, the band will kick off a sold-out, 82-date world tour with a free concert in Seoul, which is expected to be attended by more than 250,000 in-person fans and will be live-streamed on Netflix to more than 190 countries. When the tour wraps up in 2027, BTS are expected to have generated more than $1billion in revenue. Some more outlandish estimates suggest they will eclipse the $2billion haul of Taylor Swift's Eras tour.

Korea's southern port city of Busan has reportedly brought together the country's brightest and youngest in the field of artificial intelligence to share some of their innovations. My colleague Shin Ye-eun was there. If you want to learn about artificial intelligence, this is the best place to start. Hundreds of AI tech developers and enthusiasts have gathered in the port city of Busan to show off their latest accomplishments and discuss how the tech will move forward. "As you can see, there are lines of booths behind me showing how AI can bring imagination to life. What particularly caught my attention is that these booths are being run by young enthusiasts, ranging from elementary to high school students."
