There's an inevitability when it comes to technology, our mobile phones essentially becoming our personal computers, touching a piece of glass no more than 7.5mm in depth, weighing less than a pound. The understanding of "how is it supposed to help me?" takes time, but the inevitability remains, robots will become a fixture in the lives of many if not everyone in the next 10-15 years (I'm being extremely cautious but the pace of technology now could make this 5-10 years).
