The hydrogen powered robot horse farts steam constantly.

We've had robots for decades, in the form of factories. That's the right way to use them, to customize the process so it works smoothly with them. Making humanoid robots is so inefficient and limiting. The only benefit it has is compatibility with the way humans do the tasks, so they can replace us incrementally without a massive initial investment. Once humans are replaced, there's little benefit to them being humanoid and you might as well redesign things for specialized robots. Perhaps the one benefit of humanoid ones is being able to do many different tasks in a small space, and the same space the humans work in.
