On the contrary; in this case, Twitter is a symptom. Instead, the problem is bubble-based news. The platform could've been something else, like Facebook, or RSS.
A lot of people read the same things, should we all burn out?
Eventually? Would everyone burn out at an equivalent speed?
I don't know the answer to your question. I do wonder if it has to do with being closed or open minded. The difference of a person enjoying being in a bubble, and one who wants to think outside of the box.
Also, there are platforms where people gather who think outside of the box. However at some point they become so popular, that the status quo of the masses takes over. (Reddit seems an excellent example of this.) To me, it seems akin to the principles of the Temporary Autonomous Zone (TAZ) [1].
