Yes, satoshi expected adoption to take decades - but that's not how it went so he was wrong.
No, I still think he's right on that. Adoption is by far not general, and will take decades IMO.
The only thing that happened was that speculation pumped up the price way way higher and faster than he probably expected, and now we're in for a big correction after all disappointed "quickly to the moon" dreams turn out a bit premature.
The real question is: Will we modify bitcoin for faster adoption? Or will be just relaunch it according to the nature of the informationflow on the internet? Or we just tell everyone to go back home and forget about it until next 10 years?
The last part. Which was the idea from the beginning. You don't even have to TELL it anyone.
Of course a potential change in the fundamentals of money will AT LEAST take a few decades. It is much more than a technological adoption. It is a total change in the way one does finance, economy and in the perception of value and money. That takes at least a generation. No wonder Satoshi programmed the creation of the coins over 140 years.
Thinking that accepting a totally new money would be similar to the adoption of facebook is ridiculous.
Even much more modest changes took decades. The releasing of gold from fiat took almost a century. Accepting e-mail as "legal document" took a few decades since the invention of e-mail. What did you expect ?
Whether it works out or not is a big question. But the answer will not be available before a few decades.
The fast rise in price by pure speculation (essentially on "to the moon soon") is a problem, because instead of a slow rise which would have comforted adoption, we will probably witness a very long decline until fundamentals are met. A long decline history is much worse than a slow rise history.
so adorable with the fear mongering I almost want to give them candy.
