Given all this talk about the singularity and AI being able to synthesize novel proteins, how far away are we from having complete command over the human body so that any part of it can be modified. In particular:
>Increasing height by targeting every bone and muscle unilaterally, not just breaking the legs and stretching them
>Complete facial reconstruction to look however you want
>Change your organs to make them better, more effective, free of damage
>Enhance your dick so its a giant superdick
>Increase IQ significantly
Will all this stuff be possible in the next 20 years?
