According to Lex Fridman on Twitter, he has been dedicating extensive time to hands-on AI engineering, particularly focusing on programming and working with robots and hardware. Fridman emphasized the importance of direct engineering work for understanding real-world AI challenges and solutions, especially in the fields of human-robot interaction with quadrupeds and humanoid robots. He revealed ongoing collaborations between MIT and Caltech, reflecting a trend of interdisciplinary research hubs driving innovation in robotics and artificial intelligence. Fridman also noted participation in major industry events such as NeurIPS 2025, highlighting the significance of conferences for networking and knowledge exchange in the AI sector. These developments underscore growing business opportunities in advanced robotics, AI-driven interaction design, and cross-institution partnerships, as cited directly from Fridman's announcement (source: Lex Fridman, Twitter, Nov 5, 2025).
