Musk: Viral Humanoid Robot Demos Are Mostly Preprogrammed, Not Truly Intelligent

Speaking at an X Takeover interview on Oct 22, 2026, Tesla CEO Elon Musk said many impressive humanoid robot videos circulating online are largely preprogrammed or remote-controlled rather than powered by truly autonomous intelligence. He argued that a genuinely intelligent robot should be able to handle unfamiliar scenes and tasks, while a preprogrammed robot can only repeat fixed actions in a prepared environment and tends to fail when objects move or unexpected obstacles appear.

Musk described Tesla Optimus as using an end-to-end visual AI framework shared with the company's FSD self-driving technology, supported by Dojo supercomputing and trained on large volumes of video and operational data, rather than relying on hand-coded programs for each scenario.

He said the biggest hardware bottleneck for humanoid robots is the dexterous hand, since replicating near-human grasping and manipulation requires actuators and tactile sensors developed from scratch, and existing mature supply chains cannot fully meet those needs. He also warned that key components such as motor magnets carry supply-chain risks, noting that a previous magnet supply issue delayed Optimus by several months. Manufacturing a humanoid robot is harder than making any Tesla car to date, he said, because Optimus uses many newly developed parts and requires building a new supply chain, so production will likely follow an S-shaped ramp-up curve.

Musk added that the Fremont factory has set up a dedicated Optimus production line, and robots produced at this stage will first be used inside Tesla factories to collect real-world data for improving AI models, rather than being quickly sold at scale to consumers.
