Social media platforms developed very rapidly,some couldn"t catch up and feel threatened? will these platforms be here for long ?are they a must use?

yes yes yes wll remian for a long time and will evolve to he extent that it becomes difficult to live without it.

The social media shortened a lot of time, efforts and some times the money to get access to all specilities we are asking about it , for example your posts and questios on this website i knew about them while I am searching through my facebook and I found one member following you.

SO are you agree with me that the social media will be remian for a long time ???
