Will Link Building Soon Be A Thing Of The Past?
 

Not soon but it will slowly
it showing from now that social media sites are now playing important role in seo you can share your link here it will help you more then posting a link on directory sites becouse these social media sites are indexing more then any other sites

yes in some manner...

Link building can never be out dated and an old technology only one thing will change in this and that is the way of link building not the process itself.

in some manner yes
