How far off would you estimate a company like Boston Dynamics is from production then? (Say with existing levels of industrialization in the form of non-humanoid robots already commonly used as a benchmark/baseline)
Even once robots can do amazing things, there needs to be an economic use case that's compatible with what they can do, how they're powered, and how long they can work for.
Similar to quadcopters in a way - they have changed the world in some limited ways, but so far they haven't scaled up to carry people or out to deliver parcels, so they remain niche. If someone figures out one day that robots can deliver burritos/assassinate dissidents/stack shelves efficiently, it could be a quick takeoff.
