Tech leaders are busy making moves this week: Instacart's CEO Fidji Simo is moving to lead OpenAI's applications team, Hasan Sukkar is stepping down from 11x, and Tesla faces a potential trademark denial for "Cybercab" and "Robotaxi." Meanwhile, Meta announced AI-powered video ads in Threads, expanding its reach as it continues its push into AI-driven services. Elon Musk's Posha robot meal delivery is a quirky update on tech innovation.
