To be honest, the autonomous control of the robot seems like the easier part of the equation. (doing it safely in a room with guests, unguided... thats another matter). The physical limitations and packaging are a big challenge, and I dont think I saw Optimus lift anything remotely heavy.. just pull a beer tap.. a decision that probably speaks volumes about current limits of the technology.

To apply my first point to reality: put an Optimus in its current state/capability, on a commercial 0-turn lawn mower, plug Optimus into the mower's power takeoff, and have someone in another country remotely pilot the mower. That right there is worth every commercial lawn service having at least one on their crew TODAY.

The appeal of hot swapping an operator real time on the equipment you already own, whether it's a push lawn mower or a huge mining truck, provides enormous value right out of the gate. Especially in tasks where the Optimus can handle 90% of the task autonomously but needs to step aside or oversight for the last 10% of the job. Compare to a business model that requires purchase of all new very expensive and unique equipment.

I've worked in robotics for over 10 years, at state of the art labs and high quality startups.

There are really only two hard problems in robotics: Perception and Funding.

Perception, especially around a bunch of people, with depth, mapping, understanding traffic and gestures, all in real time etc etc will be a huge problem for these machines for a while.

Funding though? I doubt that's an issue right now.

I'm also a roboticist. Perception and funding are hard. But don't forget battery energy density, and the power-to-weight ratio and energy efficiency of actuators. Also very very hard, and Moore's law helps not at all.

Autonomous cars are in a nice niche since they store vast energy for actuation anyway, it's OK to be heavy, and the controls are relatively simple. They are limited by perception and decision making.

Humanoids are way more limited by energy storage and actuation. Animals are absurdly efficient.

Tangential question: are there any actuators out there that mimic the animal muscle tissue, i.e. swelling laterally in order to shorten a tendon and pull a joint? This seems like a very elegant method compared to servos with all sorts of slack and rigid positioning. I'm not a roboticist so I'm not familiar with state of the art in actuators.

They exist, but they're inefficient compared to ordinary motors.
