Cathie Wood, CEO of Ark Invest, has identified humanoid robots as the most significant opportunity in artificial intelligence, surpassing other applications such as robotaxis and healthcare AI. Speaking at an investment conference in Riyadh, Wood emphasized the potential of embodied AI to revolutionize industries, particularly in healthcare and transportation, by driving substantial productivity gains. Ark Invest's portfolio, which includes a 9.16% stake in Tesla, reflects a focus on robotics and AI advancements. Wood noted that while enterprise adoption of humanoid robots may be gradual, consumer uptake could be quicker, with personal assistants potentially managing tasks like shopping. She dismissed concerns of an AI market bubble, considering current valuations reasonable over a five-year period.
