Can Elon Musk and Tesla really build a humanoid robot in 2022?

In August 2021, Elon Musk announced that Tesla would build a humanoid robot designed to "eliminate dangerous, repetitive, boring tasks" and respond to voice commands, promising to show off a prototype in 2022. Can the company deliver on Musk's goal? Tesla has achieved a great deal since Musk founded the electric car firm in 2003: building a valuation of $1 trillion, selling in excess of half a million cars and installing a global network of more than 2000 charging stations for them. But there have also been failures and delays. Musk promised to have a million self-driving taxis on the road by 2020.
