Lets be realistic.
Bitcoin will be adopted, when its price stabilizes. The reason it is not adopted is because its price very unstable.
More adoption will cause the price of Bitcoin to skyrocket. This in turn will cause panic as people will think Bitcoin has become volatile again, or they may start to look at Bitcoin as a huge bubble. This will decrease the acceptance of the currency again and will in turn cause Bitcoin to crash all the way down to pennies and dimes.
The ideas many users are dreaming about on this forum are far-fetched and very unlikely to happen, that does not mean it WON'T happen...it's just very unlikely.
