In 10 years, will Facebook still be so popular and so dominant? What competitors might overtake it?

i think with everything that facebook is doing and what they are known for makes a big opinion cause of all its products and social media games alot of stuff they could hold their own but if were talking about other social media buying it out it could be facebook buying other social media names like skype or myspace twitter mabe pintrest but if its facebook buying others out i think it could be twitter or instagram or pintrest if they go to get off the internet
