What happened
Elon Musk said Tesla's Optimus humanoid robots could go on sale to the public by the end of 2027, priced as little as $20,000 each, calling Optimus potentially “the biggest product ever.”
Why it matters
If that timeline holds, a general-purpose robot at that price would move humanoids from controlled factory trials toward everyday use — though researchers say the machines still fail too often to be reliable, with one noting 70% success is like it doesn't work.
WHO IT HITSHome robotics startups and logistics operators weighing a $20,000 humanoid purchase face a reliability gap: today's machines mostly need remote human operators for non-factory tasks.

Musk is not alone in his evangelism. Marc Andreessen has said robotics could become the “biggest industry in the history of the planet,” and Jensen Huang said in January that humanoid robots would match human-level ability this year. Morgan Stanley projects nearly 1 billion robots that resemble and act like humans by 2050, a market worth over $5 trillion.
The gap between those proclamations and lab reality is where the debate sits. As far back as 1495, Leonardo da Vinci sketched a mechanical knight. Westinghouse's Elektro drew crowds at the 1939 World's Fair, Waseda University's WABOT-1 arrived in 1973, and Honda's ASIMO was discontinued in 2018 unable to get beyond demonstrations. Today's robots, even with advanced AI, face the same existential challenge.
