I think not just (computer) scientists but the general population thinks to serve the common good makes sense, not last because we understand it's eventually for our own good.

It is however just that very small minority of the population with highly psychopathic/narcissistic traits - those that, in pre-historic times, would have been kicked out swiftly of hunter & gatherer / small village communities because of their parasitic nature - that in bigger civilisations seem to thrive due to abstraction (distance/time of the effect of their actions) and obfuscation (PR) and instead unfortunately seem to rise to the top (CEOs, presidents, 'thought leaders' ...) to steer the world's overall economy and mindset - and steer it in the abyss.

Sometimes I think humanity was just not made to scale, and this aspect is one very large aspect of it.
