I think that 20 years is too soon
There hasn't been a significant prolongation of human lifespan by scientific methods never in history, so to believe that overnight we are going to achieve immortality is like to believe in star signs. Completely absurd
Nanomachines are actually in progress, but they are very far to achieve the efficiency to keep perfect regulation of the human body
I'm not sure if immortality will be achieved some day, but for sure not before two hundred years from now

When a real biologist/biochemist starts making these claims, then I'll start taking them seriously.
