The problem is 400 years ago people would have said exactly this about the soul.
It seems very possible the mind is just a superstitious artifact but this idea persist in various forms because to let go of it truly means the lights go out at death. We seem incredibly good at telling ourselves stories to deny that reality.
I would think the lack of boredom is still a bigger variable.
I have not felt true boredom since about 1993. Not at least in the way it felt then when there was literally nothing to do.
When the choice was to stare at the wall or go out and find something interesting to do on a Saturday night, the choice was made for you. Many other people were in the same situation. Now the choice is made for everyone but in the opposite way to more or less just stay home.
