I don’t want to bang on about this cancer of mine, and will try to avoid doing so, but a thought struck me the other day.
In the last few months I have had an endoscopy, an ultrasound endoscopy, a laparoscopy, a CT scan, a PET CT scan, and MRI scan of the brain and another one of the spine. In Isaac Asimov’s book Fantastic Voyage, and the film of the book, a team of doctors is put into a submarine, miniaturised and injected into somebody for medical reasons – and it seems to me that the doctors are basically doing all that now, but remotely. With the endoscopy and laparoscopy they are effectively sending a little submarine into the body but beaming the pictures back instead of having little people in it.
The science fiction is really now fact, except for the implausible shrinking business.
Let’s be honest, if the technology existed to shrink things to microscopic size, there is no way it would not be used for military purposes way before it got used for medicine.
