Humanoid robot?

$Tesla(TSLA.US) Many people think humanoid robots are not very useful at this stage, just a toy, and not yet ready for mass production.
I think there are several important points about humanoid robots:

1. Humanoid
   Why humanoid? Before this, there have been various specialized robots that are already in mass production and application, mostly for B2B use in factories and hospitals, with very few for personal use. Why do we still need humanoid robots? Because the world is designed for humanoids.
   Think about it: the toothbrush, cup, pen, wrench, faucet, kitchen knife, trash can, bicycle, chair, remote control, and countless other tools or devices we use in daily life all require our hands, feet, and our entire humanoid body to operate, with hands being the most involved.
   Appliances like washing machines, dishwashers, and air fryers save us from manual labor, but tasks like picking up clothes and putting them into the washer, then taking them out to dry afterward still require human effort. Humanoid robots can help with all of this.
   Another advantage of humanoid robots is that they don’t feel threatening and are more relatable. Visually, you don’t immediately perceive them as machines but as "human-like" machines, allowing them to serve as companions and caregivers in the future, becoming accepted as part of the family.
   Similarly, quadrupedal robot dogs are another major direction alongside humanoids.
2. Dexterous Hands
   Human hands are incredibly precise and dexterous, capable of almost anything. While industrial robots and robotic arms are already well-developed, human intervention is still often required. Imagine if humanoid robots had hands as dexterous as human hands—they could assist with countless tasks. Thus, robotic hands are crucial.
   The development of dexterous hands, including the forearm (which controls the fingers), accounts for nearly half of the entire humanoid robot R&D effort. The benchmark is simple: mimic and match human capabilities until they can thread a needle.
3. AI
   Why have humanoid robots regained popularity in recent years? Boston Dynamics’ humanoid robots were already impressive years ago, with many stunning videos online. However, their movements were hard-coded, written as step-by-step instructions, lacking the ability to converse fluently with humans or perform tasks independently. With recent AI breakthroughs, humanoid robots can now have a super-intelligent brain, receiving human instructions via voice recognition and navigating using pure vision technology like in cars. More importantly, they can learn autonomously—their actions don’t need to be coded line by line; they can even learn by watching videos.

Therefore, I believe humanoid robots will experience a boom in the near future.
