Joi Ito, the director of the MIT Media Lab, has resigned due to his ties with Jeffrey Epstein, a convicted sex offender. The Media Lab was aware of Epstein's status as a convicted sex offender and still accepted donations from him. Epstein's visits to the lab were accompanied by his female assistants, who were described as models and raised concerns among the staff. The incident has sparked a discussion about the ethics of accepting donations from questionable sources.
