That still falls into self interests.
Without self-bias, why would we desire to do anything?
"That'd only be possible if the reason to live was being forcibly assigned to you from someone else."
True, but it's interesting enough to see what people's interests of life are outside of themselves. If one day we escape being shackled by self bias, it'd be great to know what and why people aspire to do certain things.
People throughout time have show more inclination to work harder for a cause greater than themselves. I like to take religion, nationalism and the plethora of great sacrifices through time before this(war) as an example. I think that's where our maximum potential as a species lies.
