LLMs aren't the specific architecture you'd use, but it very much looks like a tractable engineering problem to go from a university research lab project that can manage to fold clothes as a demo, to a sellable consumer product. The timeline is gonna be off, so no one knows if it's gonna take 3 years or 30, but it's not going to take an unknown breakthrough in materials science and physics the same way that nuclear fusion looks like it will require.
