I was around in 2011, and we dreamed of this day, where the world has been exposed to bitcoin. As the saying goes "be careful what you wish for", there really isn't that much going on for bitcoin, but furthermore, the future of bitcoin.
3 years is really not to much. If you dream and imagine back then exactly as it is now, i doubt you would wrote article like this, since you would have some vision what will be in 3 years from now.
