I think Fazebook would still be around for decades, its social network on the other hand would probably become a digital graveyard, a chronicle of sorts that social scientist will use to study behavioral changes. For now the youngsters use instantgram and whatsup, tomorrow when it's some other thing they will just buy it and would get the users it needs so they probably will continue to have a bunch of data to sell to their customers. Also Facbook is more of a information company than tech giants like Googel, Microfrost and Appel. /intentionally misspelled their names btw
