Uh, out of all the things that are the bottleneck, you think it's robotics hardware that is the bottleneck?

In an age where seemingly every single robot company has a humanoid prototype whose legs are actively supported through high powered actuators that are strong enough to kick your ribs in?

In an age where the recent advancements in machine learning have given bipedal walking a solution that is 80% of the way to perfection with the last 20% remaining the hardest to solve?

Honestly, from a kinematics/hardware perspective the robots are already good enough. Heck, even the robot hands are pretty good these days. Go back 10 years ago and the average humanoid robot hand was pretty bad. They might still not be perfect today, but they are a non-issue in terms of constructing them.

The only real bottleneck on the hardware side is that robot skin is still in its infancy. There needs to be some sort of textile with electronics weaved into it that gives robots the ability to sense touch and pressure.

What has remained hard is the software side of things and it is stuck in the mud of lack of data. Everyone is recording their own dataset that is unique to their specific robot.
