Is the "Rebuild from scratch the same thing but using another paradigm" a good option to improve social? I don't have any Facebook accounts but after 15 years

Is the "Rebuild from scratch the same thing but using another paradigm" a good option to improve social? I don't have any Facebook accounts but after 15 years programming stuff, I don't see the copy/paste as a powerful solution. Also, distribution is not really the problem here. From architecture point of view Facebook is distributed. The problem is the need of store huge amount of data in the cloud and pretending that to be free.
