It took about the same amount of time to evolve human-level intelligence as human-level mobility. Pretty much no other animal walks on two legs...
We may have needed a billion years of evolution from a cell swimming around to a bipedal organism. But we are no longer speed limited by evolution. Is there any reason we couldn't teach a sufficiently intelligent disembodied mind the same physics and let it pick up where we left off?
I like the notion of the LLM's understanding being "shadows on the wall of Plato's cave metaphor," and language may be just that. But math and physics can describe the world much more precisely and, of you pair them with the linguistic descriptors, a wall shadow is not very different from what we perceive with out own senses and learn to navigate.
As for limits, in my opinion, there are a few limits human intelligence has that evolution doesn't. For example, intent is a double-edged sword: it is extremely effective if the environment can be accurately modelled and predicted, but if it can't be, it's useless. Intelligence is limited by chaos and the real world is chaotic: every little variation will eventually snowball into large scale consequences. "Eventually" is the key word here, as it takes time, and different systems have different sensitivities, but the point is that every measure has a half-life of sorts. It doesn't matter if you know the fundamentals of how physics work, it's not like you can simulate physics, using physics, faster than physics. Every model must be approximate and therefore has a finite horizon in which its predictions are valid. The question is how long. The better we are at controlling the environment so that it stays in a specific regime, the more effective we can be, but I don't think it's likely we can do this indefinitely. Eventually, chaos overpowers everything and nothing can be done.
Evolution, of course, having no intent, just does whatever it does, including things no intelligence would ever do because it could never prove to its satisfaction that it would help realize its intent.
Also, isn't that what's actually scary about AI, in a nutshell? The fact that it may radically simplify our world to facilitate e.g. paper clip production?
No, it's more about massive job losses and people left to float alone, mass increase in state control and surveillance, mass brain rot due to AI slop, and full deterioration of responsibility and services through automation and AI as a "responsibility shield".
No, but that's only a small part of what you need to model. It won't help you negotiate a plane-saturated airspace, or avoid missiles being shot at you, for example, but even that is still a small part. Navigation models won't help you with supply chains and acquiring the necessary energy and materials for maintenance. Many things can -- and will -- go wrong there.
> In other words, why are we assuming that agents cannot shape the world
I'm not assuming anything, sorry if I'm giving the wrong impression. They could. But the "shapability" of the world is an environment constraint, it isn't fully under the agent's control. To take the paper clipper example, it's not operating with the same constraints we are. For one, unlike us (notwithstanding our best efforts to do just that), it needs to "simplify" humanity. But humanity is a fast, powerful, reactive, unpredictable monster. We are harder to cut than trees. Could it cull us with a supervirus, or by destroying all oxygen, something like that? Maybe. But it's a big maybe. Such brute force takes requires a lot of resources, the acquisition of which is something else it has to do, and it has to maintain supply chains without accidentally sabotaging them by destroying too much.
So: yes. It's possible that it could do that. But it's not easy, especially if it has to "simplify" humans. And when we simplify, we use our animal intelligence quite a bit to create just the right shapes. An entity that doesn't have that has a handicap.
Meanwhile, entire civilizations in South America developed with little to no use of wheels, because the terrain was unsuited to roads.
Wheeled vehicles aren't inherently better in a natural environment unless they're more efficient economically than the alternatives: pack animals, people carrying cargo, boats, etc.
South America didn't have good draft animals and lots of Africa didn't have the proper economic incentives: Sahara had bad surfaces where camels were absolutely better than carts and sub Saharan Africa had climate, terrain, tsetse flies and whatnot that made standard pack animals economically inefficient.
Humans are smart and lazy, they will do the easiest thing that let's them achieve their goals. This sometimes leads them to local maxima. That's why many "obvious" inventions took thousands of years to create (cotton gin, for example).
Human level intelligence is, otoh, qualitatively and quantitatively a bigger deal.
We're better than most animals because we have tools. We have great tools because we have hands.
You cannot separate the mind and the body. They are the same physiological and material entity. Trying anyway is of course classic western canon.
Nature didn't make decisions about anything.
But it also absolutely didn't "all evolved at the same time, in conjunction" (if by that you mean all features, regarding body and intelligence, at the same rate).
>You cannot separate the mind and the body. They are the same physiological and material entity
The substrate is. Doesn't mean the nature of abstract thinking is the same as the nature of the body, in the same way the software as algorithm is not the same as hardware, even if it can only run on hardware.
But to the point: this is not about separating the "mind and the body". It's about how you can have humanoid form and all the typical human body functions for millions of years before you get human level intelligence, after many later evolution.
>Trying anyway is of course classic western canon.
It's also classic eastern canon, and several others besides.
In this you are positing the existance of a _soul_ that exists separately from the body, and is portable amongst bodies. Analogues to how an algorithm (disembodied software) exists outside of the hardware and is portable amongst it (by embodying it as software).
I don't not agree with that at all, but it's impossible to know of you're right, but I can at least understand why you have a hard time with my argument and the east-west difference if tradition of the existance of a soul is that "obvious" to you.
The argument is that whether consciousness is independent of a specific body or not, it's still of a different nature.
The consciousness part uses the body (e.g. nerve system, neurons etc), but it's nature is the informational exchange and it's essense is not in the construction of the body as a physical machine (though that's its base), but in the stored "weights" encoding memories and world-knowledge.
Same how with a CPU a specific program it runs is not defined by the CPU but the memory contents (data and variables and logic code). It might as well run in an abstract CPU, or one made of water tubes or billiard balls.
Of course in our case, the consciousness runs on a body - and only a specific body - and can't exist without one (same way a program can't exist as a running program without a CPU). But it doesn't mean its of the same nature as the body - just that the body is its substrate.
