This ^^I think you would be surprised. There is a lot of coexistence in the wild with many different animals, many types of animals will graze and chill in the same area because they know they are not a harm to each other. Sometimes, in the wild, there is one dominant predator that everyone is scared of, and I guess this unites all the other animals..
That's the way I look at my snakes and me. Although snakes may not LIKE it when we take them out and play with them, I think they can also definitely grow accustomed to your touch, to your habits, to your way of handling them, to the point where they recognize somebody who isnt you and is nervous, versus you. Snakes can learn to co-exist too, and when there are no visible predators for years and years of their lives, I think they can "settle" in a bit and get much more comfortable than they were when you first got them. And they will grow to realize after many handling sessions that they always get to go back in their comfy little cage.
