Actuators alone eating 30 to 40 percent of total hardware cost is the number that keeps stopping me in my tracks when I look at humanoid cost structures. For those of you tracking this space or working with robotics hardware: do you see that ratio shifting meaningfully in the next two to three years, or is actuator cost the structural ceiling that determines which use cases actually pencil out?

The piece highlights that electric actuators waste 40-60% of input energy as heat, which forces humanoid robots into duty cycle limits before a full industrial shift is complete. I'm curious: do you think thermal management is the critical bottleneck holding back humanoid deployment in real industrial settings, or is it just one of several equally significant barriers?

Actuators are essentially the muscles of humanoid robots, converting stored energy into movement at every joint. As manufacturers race to scale production, which actuator technology do you think will win out: electric motors, hydraulics, or something else entirely? I would love to hear what you are seeing in the market or reading about.
