Is it wrong to think of how shafted the world will be if we solved the "big killers" in terms of the main human illnesses, diseases etc?
I know that if I had cancer or aids I probably wouldnt be saying that, but its kind of true.
We need some nasty diseases simply because it keeps our immune systems up and running.
There is a difference between diseases that kill and those that cause disablement, the latter, if we can get rid of them will save us, as a country, lots of money.
Cancer is the body vs itself, not an external organism, although the cause can be an infection. Getting rid of cancer will allow other options, all the money presently spent on cancer treatment can be redirected to other things. Hopefully they will eventually develop bacteria or viruses that patrol the human body specifically to kill cancer, then the present rather nasty treatment options for it can become a thing of the past.
