Dear fellows of Twiv,

It is my understanding that us humans live in peace and symbiosis with some bacteria. Is there any such arrangement with any virus?

Another way to phrase the question; if all viruses were to be removed from the world, would we be better off?

A follow-up question, even more abstracted from the lab bench; if all viruses were gone, is it reasonable to believe that new ones would come into existence? How fast? From where? In one of the twiv episodes someone said “Any suffciently complex system has parasites”, so I assume given time something is bound to fill the niche of viruses.

All the best,
