Whatsapp, Instagram and Snapchat are already far in the process of obsoleting Facebook and scooping up leaving and young users.

2 of those 3 are now owned by Facebook

Also, Snapchat has been neutered by Facebook closely duplicating their features in Instagram.

They can ape features but I feel less inhibited sharing content on Snap than I do on Facebook nowadays.

And how long until Instagram suffers the same fate?

They have already been decreasing of the charm of Instagram by adding more and more features… Basically, turning it into Facebook. In the large circle of artists that I work in, a slogan that is being oft repeated lately is “make Instagram chronological again”. I do use Facebook, but I don’t post much content as when I do, it’s almost useless because they don’t show my content to anyone. Instagram is increasingly the same way.

I think demise of Instagram is bit far off.

I'm traveling the world right now and observing people on the street and a lot of people browse Instagram more than any other apps.

I wouldn't be so sure about that. It is definitely ripe for disruption (and I've been saying that for a while) but on its deathbed? Far from it.

I don't think it will be disrupted. Facebook is like world of warcraft. I don't think there will be another in the same way again.

The only thing I use it for is messaging people whose phone number I don't have and a couple of groups that have events near me.
