It certainly could and did for thousands of years... but it would be very different. If facebook went away you would just get other companies springing up to fill the void (Snapchat, Tiktok, etc). That’s how you know it’s a core need.
I don't understand how "it would be very different" if other companies were to just spring "up to fill the void."
Doesn't this phenomenon merely indicate that some market forces believe that the industry Facebook works within has potential for more profits than are currently being extracted?
Reading these posts full of hyperbole, one would think human society couldn't exist without Facebook.
