martin joins me, author of "rise of the robots", as you heard, bill hibbert in the last segment talked about how we first thought mundane tasks would be replaced by machines, now higher order ones are. should we be worried. >> yes, there has been a lot of hype given to the issue of superintelligent machines doing things like taking over. we hear elon musk and steven hawking worrying about that. that lies in the future. the impact on jobs is happening now, it doesn't require sign for example technology, just an extension on what is happening. most workers in the economy do relatively routine predictable things, which is suited to robots and algorithms and technology. we'll see a big impact over the there. >> are we in a position where we have to take the good with the bad? i mean we like the fact that a blood monitor can test our sugar and but just the right amount of insulin into our mix so we remain upright and alert. we like that. we don't have to say machine, manage my blood sugar, it does it without us thinking about it. >> that's right. it's a dual ench sword. -- dual-edge sword.
