Who will win the race to develop a humanoid robot?

For now entrepreneurs are focussing their efforts on humanoid robots for warehouses and factories. The highest profile of those is Elon Musk. His car company, Tesla, is developing a humanoid robot called Optimus. In January he said that "several thousand" will be built this year and he expects them to be doing "useful things" in Tesla factories. Other carmakers are following a similar path.
