Ultimately whether or not it is possible to replicate the human mind in software form (doubtful imo but whatever), robots are expensive. They're good for simple, high volume tasks like an assembly line where by volume alone you can still make a profit despite high operating costs, but for something like construction where you have a lot of varied, smaller tasks, and the division of labor is less economical and therefore less conducive to the individual niche of a given robot, humans are cheaper even when you factor in sick days and weekends and stuff.
Also, you have to pay humans, but there are operating costs associated with running a robot. Power isn't cheap.
People freaked out about industrialization, the lifespan increased and people still had jobs. People freaked out about computers. Now most people own a phone and still have jobs. People freak out over robots and...
Either way the rumba still hasn't bankrupted every cleaning business. Whether or not you believe the brain can be programmed into a computer, I find it unlikely that machines can ever do much more than aide humans in most instances.
