"The information needed to cure cancer most likely simply isn't known yet"
That statement is true. the fact of the matter is that the entire medical community don't know how to cure it and probably never will (without computers). if they continue their research they won't find the solution. it is through computers that the cure can be found.
i don't know if you ever heard of "intelligent drugs" before but it is a combination of nanotechnolgy and computer software. It uses cell machines to create an antibody for any virus. The cell machines are programmed to do specific things in the human body such as search for cancer cells, search for Aids virus, destroy cancer cell, destroy AIDs cell etc. It modifies its composition based on the virus and adapt with the virus so killing it is very easy.
Now, with this intelligent drug all human diseases including cancer and HIV are solved. Any epidemic can be cured because the drug adapts. Although my human level artificial intelligence program don't have anything to do with this intelligent drugs, the components that make up my program can help in the technology.
