Here's the robots in action.

I wonder how far away we are from humanoid robots that can perform most unskilled or semi-skilled work? Cleaning, factory work, stacking shelves etc etc

When you look at this it doesn't seem that far away.

I would also guess that if Chinese manufacturers can make and sell hatchback cars for 10,000 dollars they will be able to make robots like this for less.

When that day comes, we will very quickly have a new type of society and economy, though who knows what that will look like.
