I'm curious as to what would be the most scientifically accurate way in which to turn ordinary people into superhuman beings that one would refer to as "superheroes" or "supervillains."
A few notes
- "Superhuman" in this case meaning someone obviously more capable than an unaltered person could achieve through extreme physical/mental exercise, or possessing abilities unavailable to unaltered people
- Additional consideration will be given as the complexity of the power increases. Unaided flight is better than a guy in a strength-enhancing exosuit, for example
Please stick to current scientific knowledge and technology that could reasonably be invented in the next decade or two.
