 the agility of the fingers, the sensors, all that is making significant improvements, as well as becoming cheaper and cheaper. There's a company that used to sell humanoids for about $150,000, and they just released a new price for the new model, and it's $16,000. So you can see the hardware getting better, and the sensors are getting better. But then on top of that, like we talked before, there is the software, there's the intelligence.
