I think we will come up with a cure for HIV/AIDS. There are some very good scientists working very hard on this problem, and they are coming up with advances all the time. It is a very difficult disease to treat however, so the best treatments take a long time to research, perfect and be tested.
AIDS is no longer a fatal infection and can be controlled very successfully with drugs and AIDS victims can live without any restrictions and die of natural causes not related to their illness. It is an incredibly complex virus as it attacks the very cells that we use to fight infections, one thing that we can all do is prevent the spread of AIDs by always being careful and practice safe sex at all times. This will reduce the spread as this is an infection and not a mutated gene like so many other diseases can be triggered from, everyone can do something to reduce the spread of AIDs as scientists continue to work on even better treatment and potentially a cure.
This is a big question primarily due to the fact that HIV will (and has) mutate into newer forms and so newer remedies are required. There has been a significant amount of progress over the past 15 years in HIV drugs but it is still a matter of out-living the disease. The good aspect of treating HIV is that we have a number of targets to aim at because it has to enter the cell and you our own machinery to copy itself. If we can stop this it stops the virus.
