Alexa Architect Rohit Prasad Named CEO of Boston Dynamics

Rohit Prasad, the Amazon executive who led the company's artificial general intelligence division and helped build Alexa, has been appointed CEO of Boston Dynamics, the company announced earlier this week. The move puts a proven consumer-AI product builder at the head of a humanoid robotics firm whose owner, Hyundai Motor Group, plans a factory capable of producing 30,000 robots per year by 2028.

"Boston Dynamics is uniquely positioned to advance physical AI through its world-class robotics expertise," Prasad said in a statement. "I am honored to join the company at such a pivotal moment for the industry."

Why does this appointment matter?

The hiring lands Prasad in one of the most competitive corners of technology. Tesla wants to lead humanoid robotics too, and its CEO Elon Musk has made sometimes outlandish claims about the ambitions of the company's Optimus program — including talk of scaling production dramatically. Prasad's progress at Boston Dynamics will inevitably be measured against Tesla's.

The economics of the field remain demanding. Boston Dynamics's Atlas humanoid robot currently costs between $130,000 and $140,000 to produce, according to the Korea Herald. Even after mass production begins, the expected price is around $30,000 per unit.

What did Prasad build at Amazon?

Prasad built his reputation turning AI research into products people actually use. He started his career at Raytheon's BBN Technologies, leading machine-learning research on real-world applications: speech-to-speech translation, psychological health analytics, document image translation, speech recognition, and text classification.

His fascination with computers people could talk to traces back to childhood viewing of Star Trek, as the Wall Street Journal has reported.

At Amazon, Jeff Bezos dreamed up Alexa, but the company's early efforts to build the assistant did not go well. Prasad helped lead the push to incorporate deep learning into Alexa, allowing the system to improve as more people used it and generated more data. It took longer than Bezos wanted, but Alexa amassed an enormous amount of speech data and became one of Amazon's most popular products. Prasad later rose to senior vice president and head scientist for AGI.

How does Prasad think about AI?

Prasad has long argued that AI should be judged by usefulness, not imitation. In a 2020 column for Fast Company, he called for retiring the Turing test, the famous measure of whether a machine can exhibit behavior indistinguishable from a human's.

"It is time to retire the lore that has served as an inspiration for seven decades, and set a new challenge that inspires researchers and practitioners equally," he wrote.

In an interview three years ago, he explained the standard he prefers: "If you came in and said, 'Alexa, I'm feeling hot here' or 'I feel this is too warm,' it should come back and ask you, 'Do you want to turn down the thermostat or lower the temperature?' It shouldn't tell you to go to the beach. This is why AI is such a hard problem, because the context is so crucial."

Can Alexa's builder sell robots?

Boston Dynamics's first humanoids target industrial work. They will initially handle tasks such as welding and logistics before potentially moving into more complex parts of manufacturing, including component assembly. Home robots remain much further off, given current production costs.

Prasad's record suggests he may push toward consumer markets eventually. Seven years ago, he was already arguing that Alexa would become smarter if it had a physical form.

"The only way to make smart assistants really smart is to give it eyes and let it explore the world," he said in a presentation at MIT Technology Review's EmTech Digital AI conference in 2019.

Now, with Hyundai's 30,000-robot-per-year factory plan on the horizon for 2028, Prasad gets the chance to test that theory at industrial scale.
