$DUOL CEO Luis Von Ahn addresses the concerns about Apple and Google translation displacing their business. Along with my Mom Claude Coding a Duolingo replica before 9am, this is the premier bear thesis. This bear thesis has been around for 10 years and has yet to materialize.

Duolingo founder on the key to solving retention “The way we solved [retention] was just through trial and error,” Duolingo founder Luis Von Ahn explains. “By now, some of us have some intuition about what is good for gamification, but the reality is that most of it is just trial and error.” He continues: “In the history of Duolingo, we have run 16,000 A/B tests. Each one of those is trying to figure out if we change these little things — “should this button be red or blue?” — to try to get you to come back. And its these 16,000 A/B tests that have made our retention outstanding. At this point our user engagement is starting to get comparable to social networks.” Source: Stanford Graduate School of Business (May 2025)

Theo Von: “Am I crazy to think that there’s a country that’s killing a bunch of children … ” “The government of the country that’s done this seems to own our country … ” “The same country has used a lot of tech companies and scary technology … ” “And some of those companies are now in bed with American surveillance?” “The same companies that are doing the technology that’s part of the murdering in Gaza … have surveillance and technology contracts in our country.” “That seems scary.” “If they’ll kill the people right next to them, what would they do to people here?” “It gets real scary.” Theo Von

no because duolingo being the main sponsor would make so much sense, their promo is actually funny and it's connected with eurovision because I feel like we all at some point started learning a new language on duolingo because of our favourite eurovision act

Ryan Clark on Eli Manning not being selected to the Hall of Fame in his first year of eligibility: "I thought that obviously, they clearly had people in that room with common sense. It's no respect to Eli Manning. I'm not gonna be in the Hall of Fame conversation. But I do love the game of football... if there has to be some deliberation on whether or not this person is worthy of being a first-ballot Hall of Famer, I don't believe that they can be."

#PerfectCrown character introductions from the cast #IU: Huiju is a character who believes she has everything except status. She has lived without lacking anything, but after meeting Lee Ahn, she begins to experience new events and changes in a completely different world from before. I hope you look forward to Huiju’s transformation. #ByeonWooSeok: Lee Ahn was born into royalty, but aside from his status, he is someone who cannot have anything else. Although he receives the love and support of the entire nation, he is also the one acting as regent in place of his young nephew, the king. He is used to hiding himself, but after meeting Huiju, please watch closely how he begins to change. #NohSangHyun: Jungwoo was born into a prestigious political family and became a prime minister at a young age. With his outstanding abilities and gentle personality, he is popular among the people. He is a close friend of Lee Ahn and shares a deep connection with Huiju from their time at the royal school. However, news of their marriage shakes Jungwoo’s heart, and he eventually comes into conflict with his longtime friend Lee Ahn, both as a politician and as an individual. Please look forward to how the relationship between Jungwoo, Lee Ahn, and Huiju develops. #GongSeungYeon: Yirang was born into a family that has produced four queens. She values her family and the royal household over individuals. She has a son who became king at a young age, and as Lee Ahn serves as regent, she constantly worries that her position may become unstable and keeps him in check. When Lee Ahn declares he will marry Huiju instead of the match she arranged, her feelings grow complicated. Please watch what choices she will make to protect her son and herself. #21세기대군부인
