I believe the technology shown in the movie is necessary in out future as long as the technology is controlled by right people. As we saw through the film, Will, himself, has super power. He can grow trees, make people healthy, change weather, and even control other people. If this power was controlled by wrong person, he or she would used it to rule over the world. However, Will used the power to purify water, heal people etc. We need this power in the future but only when it’s under right people’s hand.
I also believe uploaded-Will is the same as real human-version of Will. He used his power to save the world. He purified water and air, and he also tried to protect his territory against violent terrorists. The movie described the terrorists that as if they are saving the world from Will’s cyber attack. However, we should not forget that the terrorists killed the innocent scientists and even tried to kill civilians. They should not be expressed as heroes. I believe Will was doing the right things.
