The extract you have describes the benefits of using nanobots. Your partners extract presents a totally different view. Find out what information your partner has by asking questions. Share your information with your partner. Discuss the prospects of using nanobots.
One of the goals of modern technology is to build nanobots. The possibilities for pollution control and clean-up are startling. It would no longer be necessary to destroy the biosphere in an attempt to gather raw materials for production. Any substance nearby would be broken down into atoms and reassembled into desired products using the sun as an energy source. There would be no manufacturing waste. 100% recycling would be achieved because the nanobots would be able to construct and de-construct atom by atom. We would be able to build planet mending machines to correct damage already inflicted on the earth. We would also be able to make use of all the garbage we have already created. It will even be possible to repair living tissue and extend human life. Nano-computers could be inserted inside living cells. These computers would watch for invading organisms and if a virus or some other alien organism were found, assemblers could be sent out into the bloodstream to attack and destroy them. In the home, all appliances would be replaced with a bread-box sized machine called a "shape shifter." This machine would take the place of all the other appliances and would be able to perform any function you asked of it. It could cook dinner, be the toaster, microwave, or can opener, or create the food for you.

One of the goals of modern technology is to build nanobots. Unfortunately, nanotechnology could be misused or abused. As the nanobots construct or deconstruct products atom by atom, molecule by molecule, billions of them could easily reduce the biosphere to dust in a matter of days. Another obvious potential problem is the use of nano-machines by individuals or groups with ill will in mind. Their options are frightening, including new kinds of weapons, designer viruses, and unimaginably thorough surveillance of our thoughts and actions. In the hands of a totalitarian state the implications are fairly obvious. Advanced technology will make workers unnecessary and genocide easy. In addition, nanobots could be influenced by software viruses and other hacking techniques.
And that is the crux of the matter. Nanotechnology promises to provide anything that mankind might ever wish for. It has the power to carry us into a startling new era. One of abundance and wealth for everyone. It would be the most powerful technology we have ever created. But it could also be the most devastating.
