Hello @samee
I believe that Steemit cannot replace Facebook. Facebook will always has its users.
No piece of Innovation ever replaces the previous one.
When the Television came out, people said the radio will die but it is still here. The same thing happened when it was said that the Internet will sabotage TV.
But TV still has its place and the Radio is coming back strongly in the form of Podcasting.
That is why I have huge hopes for d-sound.
Voice on its own is powerful because it gives people to do one thing that they love and that's Multitasking.
The Fact that Someone who works a 9-5 can listen to audio books or tutorials on things that matter to them while driving to and from work is amazing
