Luis von Ahn is the cofounder and CEO of Duolingo, a popular language-learning app with more than 31 million monthly active users. Von Ahn led the development of "Birdbrain", a machine learning model that estimates a user's language proficiency and then personalizes exercises. In 2023, Duolingo launched a new "Max" tier for its language-learning users. This year, Duolingo launched a Video Call feature where learners can practice talking in real time with an AI character. Von Ahn is a former computer science professor at Carnegie Mellon University and the co-inventor of CAPTCHAs, the way to determine if a computer user is human.

The chosen location for the two-day conference has a special association with the man considered by many to be the father of modern computer science, Alan Turing. Before 1938, Bletchley Park was a mansion in the Buckinghamshire countryside built for a politician during the Victorian era. "What Alan Turing predicted many decades ago is now coming to fruition," she said, referring to his research into machine learning. "What happened at Bletchley Park eighty years ago opened the door to the new information age," Donelan said. Since then, men and women cautioned or convicted under historical homosexuality legislation were pardoned under what is known as the "Alan Turing law."

A report from Europol expects a mind-blowing 90% of internet content to be AI-generated in a few years. A report from Europol, the European Union's law-enforcement agency, expects a mind-blowing 90% of internet content to be AI-generated in a few years. And while AI bots have telltale signs now, experts indicate that they will soon get better at mimicking humans and evading the detection systems developed by Menczer and social networks. While misinformation has long been a problem with the internet, AI is going to blow our old problems out of the water. But security researchers have discovered that the AI bots in your apps and devices might steal sensitive information for the hackers.

These are called CAPTCHAs – an acronym standing for "Completely Automated Public Turing test to tell Computers and Humans Apart." Except some cybersecurity experts say in addition to the problem of human user annoyance, there's a problem with the underlying approach to cybersecurity. How machines are becoming more like humansAs a standalone cybersecurity tool, CAPTCHAs can be unreliable because of their partially behavioral-based approach. Bots can be programmed to call out to the human solving farm overseas that decipher the CAPTCHA, all in the timespan of a few seconds. In today's world, CAPTCHAs used without any additional layers of cybersecurity protection are typically not enough for most enterprises, said Sandy Carielli, a principal analyst for Forrester.
