Elon Musk stated that a production line capable of producing 1 million Optimus (Tesla Bot) robots annually will be built in Fremont, and another line with an annual capacity of 10 million units will be built in Texas. This marks the beginning of humanoid robots being mass-produced on the scale of cars. The Optimus robot currently has functions like walking dogs, taking care of kids, mowing the lawn, and dancing. It's expected to sell for 150,000–300,000 RMB each. Would you buy one?
