Apple's brain drain in the realm of artificial intelligence continues to escalate, as Zhang Jian, the Chief Roboticist spearheading robotics technology, has confirmed his departure to join Meta's Robotics team. This high-profile shift follows the recent exit of three researchers from Apple's large language model team, who have since joined OpenAI and Anthropic, respectively. Internally, Apple is grappling with strategic uncertainty over whether to lean more heavily on external technologies or persist in developing its own models. This indecision has taken a toll on team morale, contributing to a significant loss of talent.
