Many in the last wave of bitcoiners allowed jealousy to blind them and do not see the fact that they are effectively in the same position as the early adopters were in.
i still think that anyone getting in now IS an early adopter...
I would not say nothing has happened since 2010. There seems to be much better infrastructure around bitcoins now than when I started using it in 2011, they are more useful and easier to use now.
I'd say we've been moving too slowly, with lots of amateurish and naive mistakes and empty promises. In this technological era, four years is a long time. It's time to grow up.
It may seem slow now looking forward, but I'd say going from a brand new currency four years ago to a $1.1 billion dollar market today is pretty damn impressive. Yes, some bitcoin businesses are succeeding, others are failing. That's totally normal. Remember that something like 90% of businesses that are started fail, so this isn't any different than any different market.
