As the future progresses, the people have decided that in order for the human race to exist, the humans themselves have to become machines, so they created a company known as InstaTech. InstaTech was a famous building, insuring that anyone will be able to become immortal with one flip of a couple of buttons.
All the company has to do is zap the customer who walks into InstaTech with powerful lasers, and their body will become coated in magic metal, while painting them back to their original skin color. Even their clothing gets coated, while at the same time gets repainted. As the people develop the power to become machines, they start becoming vehicles, appliances, and even robots that can be used in warfare, and other stuff. Unfortunately, there's one problem. The people can only transform once, and a while, and change back.
