Great points. Its fascinating to see the development of technology over the years.
it took facebook and youtube about 20 some odd years after the birth of the world wide web before these projects became viable. It wasnt until the 1st web killer app gained enough traction and network effect to make social media a workable product.
As for crypto payments and money is the killer app. It wont be until this function gains traction and a network affect that we will able to see the more esoteric uses of blockchain take hold.
Exciting future ahead!
Thanks!
