Sure, if bitcoin is accepted it would change the world, spur unprecedented economic growth, etc. But it is reasonable to say that acceptance will take time. Ten years, twenty, who knows?
I believe it takes 4 or 5 years for wikipedia to mature, and less than 10 years that people start shutting up about wikipedia and accept it as part of daily life.
Bitcoin will grows the same way, as it benefit from network effects.
Personally, I estimated a 49 chance of death and 51 chance of extremely wild success in a 5 years period.
