Inventions that Improve Quality of Life

For the last few years, Time Magazine has been doing features on the best inventions. Here are a few they have highlighted recently:

- a human organ printer
- an Iron Man suit
- a driverless car
- the AIDS vaccine

Out of these four inventions, which do you think will do the most to improve the quality of life for all humanity? Why?

I think both the human organ printer and the AIDS vaccine could be things that can really help quality of life in the health area. Many diseases that are "incurable" at this time can be "cured". The human organ printer could help majorly in areas such as cancer and major injuries like burns for example. And because a new organ can be printed, it will speed up the process of treatment tremendously but also protect the body from all the harmful drugs and chemicals used. This will then also make the body stronger, which will prevent other diseases from effecting the individual. And of course, an AIDS vaccine, is good for self-explanitory reasons. - It will stop the spreading of this wide spread disease. There are negative aspects to these, but hopefully we can find away to work around these and work on improving these so that these inventions can really be used to the maximum benefit.
