https://en.m.wikipedia.org/wiki/Ancient_history

"Ancient history covers all continents inhabited by humans in the period 3000 BC – AD 500."


Wait, you mean 'ancient history' doesn't cover all time between the invention of pottery and the invention of node.js?


I don't know why the invention of node.js tickled me so much but here we are. Thanks for writing this comment. Paired perfectly with my morning coughey.


From a quick read of the model used [0], it seems to simulate neurons and muscles at a functional level (not atoms or cell internals).

What I don't understand is where is the memory? How does GPT-3 or ChatGPT remember so much information with just that architecture? It would seem that the maximum it could remember is 2048 words.

EDIT: Maybe it's 2048 x 96? Still seems low for what it can do.


300bn weights, at 4bytes/weight is 1.2TB


Yes, but how does it remember the stuff you told it earlier in the conversation? Those 1.2TB is the trained model, and I assume that those weights are not changed by the conversation?


I believe that the previous input, from earlier in the conversation, is always prepended to the new input.


I'm fairly sure GPT-3 can't do any of that, because it was trained only with text. That is, it was trained without the context we are exposed to. Now imagine if it was trained with a body (similar sensors to what we have) in the real world. I'm not so sure we wouldn't get something indistinguishable from a human.


That would be a different story. Imagine its parents trained it or trained itself on data derived from the environment mixed with other bits we could already call its experience. Imagine it then went to some kind of kindergarten with others, then school, them started to look for a partner then a job and so on. Yeah, in that sense we’d be going full circle replicating the life of humans on silicon. If I were still around Id be befuddled as why we went on this track


Depends on the model used. Some models say we already have 2C locked in: https://www.ecowatch.com/greenhouse-gases-paris-agreement-26...


Does anyone have references for these claims? Particularly:

> pH will drop to pH7.95 by 2045, and most marine life in our oceans dissolve.


pH could drop to 7.95 by mid-century, according to the latest projections: https://bg.copernicus.org/articles/17/3439/2020/.

The second part of the sentence seems fictional. I don't think there is any support of that from a basic understanding of carbonate chemistry.


Found something that could in fact trigger mass extinction due to acidification [0,1], however not on the stated timeline.

I just want to correct some comments that say we are certain there are no local variables and that they have been ruled out experimentally.

This is false information and even Bell himself knew it:

"There is a way to escape the inference of superluminal speeds and spooky action at a distance. But it involves absolute determinism in the universe, the complete absence of free will."

https://en.wikipedia.org/wiki/Superdeterminism#Overview


That's not local variables, that's a global conspiracy. And it's an unfalsifiable cop-out to the problem.


Regarding global conspiracy:

"Explicit construction of Local Hidden Variables for any quantum theory up to any desired accuracy"

https://arxiv.org/abs/2103.04335

Regarding unfalsifiable, from [0] "If engineers ever succeed in making such quantum computers, it seems to me that the CAT is falsified; no classical theory can explain quantum mechanics." By "such quantum computers" he means computers that can run Shor's algorithm. "...but factoring a number with millions of digits into its prime factors will not be possible – unless fundamentally improved classical algorithms turn out to exist."

[0] - https://arxiv.org/abs/1405.1548

Now, this does not mean these theories are ready, but they are being worked on.


Physicists have a term for conspiracies, they call them symmetries.


I'd say superdeterminism is an even stronger version of global hidden variables


Okay, I just want to correct you that superdeterminism is not a local hidden variable theory.


"Explicit construction of Local Hidden Variables for any quantum theory up to any desired accuracy"

https://arxiv.org/abs/2103.04335

Or right in the page I linked: "This makes it possible to construct a local hidden-variable theory that reproduces the predictions of quantum mechanics, for which a few toy models have been proposed."


From Wikipedia about superdeterminism: "By postulating that all systems being measured are correlated with the choices of which measurements to make on them, the assumptions of the theorem are no longer fulfilled"

By assuming superdeterminism you can indeed construct a valid local hidden variable theory. But there is no way you can say superdeterminism is by itself a local theory, and no physicts will call it so. It's as far from "local" theory as possible, it's actually global.


So, what is supposed to be wrong with "the complete absence of free will"?

It reads like some sort of religious objection. If the data leads you there, you go there.

Sabine, particularly, goes there. Apparently there are no actual problems with giving up the illusion of "free will", whatever the hell it was supposed to mean in the first place.

Distaste seems pretty rich coming from people promoting MWI.


Chess is superdeterministic as all the moves are known in advance, but free will is still there. The "reality" might be such a superdeterministic playground that simply tells what the possible next moves are, while the players keep a pointer to one "chess" position and advance it one step at a time with their free will.


Perhaps the most important notion of semantics is that of referent. Pretty sure you can't develop that without an agent that can interact with the environment.


Not exactly Prolog, but there is miniKanren. You can check a list of implementations here: http://minikanren.org/#implementations


I did something like you. I also faced many of your issues and to solve it, I was also super focused on me, me, me. Trying to be better, more motivated, healthier, more exercise, better sleep etc etc.

Now that I know myself better, I realize I need to be integrated in a community with similar objectives, even when doing individual work. Otherwise, creative and/or research work is too demanding. However, everyone is different.


> I realize I need to be integrated in a community with similar objectives

How do you find such a community?


Depends on the community. For research, check your local university. You can ask around in relevant departments. Don't be afraid, some researchers are more than happy to collaborate.
