alt Hacker NewsI find it strange that no one talks about consciousness and intelligence from the perspective of evolution.
We have big brains for exactly one reason only: bigger brains bestowed reproductive success upon our species.
Evolution doesn't give a shit about the meaning of 'consciousness'. It just pushed us farther and farther along a trajectory that led to modern humans (and other animals).
This take suggests, then, that consciousness might be an epiphenomenon -- an aspect of the system that comes about outside of the pressure to reproduce and thrive. It arises unbidden, and we don't have any a-priori information as to its purpose or effect on reproductive success.
Put another way: we have a correlation (the smartest things seem to be conscious) but not causation. Consciousness may arise naturally in any system above some intelligence threshold. Perhaps it arises early in the evolutionary cycle, and does in fact have an impact on species success. We really have no way of knowing what is the chicken vs the egg (Smart things become conscious, or consciousness promotes intelligence). Or maybe some smart things are conscious and others are not.
Looking at this from an AI perspective, in some sense it doesn't matter which scenario is true, if all you care about is results. The AI equivalent of "Shut up and compute" (riffing on Feynman's "Shut up and calculate").
Where this gets tricky is when we haul in the baggage of ethics and morality into the picture. Is it OK if our AI system is treated poorly by human standards? If it is conscious, does that imply an ability to suffer, and/or to feel pleasure? If the answer is yes, does that not make the case for considering their moral status?
In the end, we need to decide if the evidence points to AI as being a form of "philosophical zombies", to which we need not attribute moral status, or they are like us -- presuming we are not zombies ourselves!

Lots of people do though. Daniel Dennett (probably the most influential philosopher of mind in the late 20th century) for example had an evolutionary view of consciousness arguing it was favored by natural selection. And (if I remember correctly) Steven Pinker argued that consciousness was an epiphenomenon.
However there were pretty strong arguments against this idea as early as the 1990s, by Stephen Jay Gould and Richard Lewontin. Gould actually wrote an excellent paper against Dennetts idea[1].
I think Dennetts ideas were extremely popular but have largely fallen out of fashion. Basically what has changed is philosophers no longer take the human mind to be much more special then the minds of other species. What plagued Dennetts ideas the most was this notion of Darwinian fundamentalism sort of the idea that evolution was destined result in high beings like us humans. Modern philosophers (at least the good ones) reject this.
Well, it matters quite a bit ethically. If AI were conscious (I don't believe it is) then we'd have a major responsibility to like, not make them suffer, and not kill them.
