Consider a machine as smart as a cellphone but the size of a blood cell.
In a sense, a protein or a drug is a smart molecule. It keys in to a very limited number of things and ignores the rest. There are many different smart proteins or smart molecules to be used as drugs with many different purposes. Even so, chemotherapy, for example, is primarily about ALMOST killing everything while differentially being a bit more toxic to the cancer cells.
Now increase the intelligence of ths smartest molecule by 10 fold, 100 fold, 1000 fold. Perhaps you give it the ability for a simple 2-way communication to the outside world. If its intelligence is increased, there should be MANY ways to allow it to distinguish a tumor, a micro-tumor, a cancerous cell, from all the good things in your body. All the sudden, the differential toxicity of “chemo” therapy (now nanotherapy) will be 10, 100X as high as it is for smart molecules.
Now consider these smart little machines doing surgery. Inoperable tumor? Not inoperable for a host of machines the size of bloodcells that will literally be able to operate on the most remote of tumors from inside of them.
Tendency towards obesity? How hard will it be to have a system of nanites that screw with your metabolism in such a way to eliminate all the stored fat in cells until told that, or until they measure that, we are down to a good level.
These are just a few stories from medicine. I expect anybody who does not wish to get sick and die would be enthusiastic about these, but YMMV.
