Doesn't it all come down to: Coming up, and being able to make, something useful, that people actually want? Robots have an incredible potential to be helpful for us, but just looking at that social-media Jibo robot, I'm not really sure why I would need that. Think about Vacuum robots on the other hand. It's still a small niche, but there's a lot of potential. I'd like to see some improvements in that direction, like if they were smarter, with better robotics & movement capabilities, they could be self-sustainable (charge themselves and empty their garbage bag etc.). Could do more tasks, remove dust, or check on things, turn off lights when you are gone... you can come up with some many things here.
