| In my opinion it's much more likely that sentient beings apathy themselves into extinction. Humans already show a tendency towards addiction to technology that exploits dopamine triggers, as social networks like Facebook do. Now imagine a world in which matrix style neural implants give you all the dopamine fulfillment that you want with no need for any effort. And combine this neural implant replacement for reality with extensive automation and AI that replaces the need for physical and mental effort. With an ever decreasing amount of stuff to do in the real world more people start hooking up to the matrix. It's quite likely a massive portion of the population will dream itself to death without accomplishing anything or giving birth to a new generation of offspring because work, invention, and sex in the real world could never compete with the feeling of something that is tied directly into your brain making you feel like you just solved the world's hardest scientific problem, or ate the best meal ever, or had the best sex ever. It seems probable that such neural implant tech and automation could be created long before a practical interstellar travel solution is created, which would also be a depressing, but realistic explanation for the Fermi paradox. |
It's an interesting insight but I can't really see it happening the way you describe.
There are already many substances (opiates, crack, meth to name a few), some that have been around for centuries, that give intense dopamine-release rushes.
Yet, only a small percentage of people, around 5-10%, seem to have the addictive personality required to completely disengage from reality and destroy their lives with these substances.
The human species has millions of years of evolutionary programming to survive the nuerodystopia you predict.
