Imagine shopping an e-commerce store with a friend, virtually trying things on your avatar that's representative of your likeness and conversing in real time with that friend, all while on the go in different places.
We're already seeing increased personalization, more individual-to-individual communication, more humanlike algorithms and more specified, diverse social platforms. I think those trends will continue in the future. I see more of a divide happening between socializing and publishing via social media, and platforms like Facebook that merge the two will probably need to pick a lane and change significantly.
