"Science of the Total Environment" journal? 🤣🤣🤣🤣🤣 Too silly even for a 3rd-rate sci-fi film...

Cheers! Got a bit clearer now.

Looks very promising! thank you for sharing. Seems worth trying and supporting.

Agree (you made me think of the famous face on Mars). I mean that more as a joke. Also there's no clear threshold or divide on one side of which we can speak of "human intelligence". There's a whole range from impairing disabilities to Einstein and Euler – if it really makes sense to use a linear 1D scale, which very probably doesn't.

Yes, the purpose isn't sabotaging.

This is so cool! Not just the font but the whole process and study. Please feel free to cross-post to Typography & fonts.

Had never heard about Graphite, thank you! I'll try to stay updated about it. But please feel free to post important news about it in this community, whenever there'll be steps forward.

Absolutely amazing!! I suppose you've seen some renderings like this one.

However, these molecules don't really have a will or a scope, and in fact I don't like how they are deceivingly represented in some of these animations. These animations show, say, some aminoacid that goes almost straight towards some large molecule and does this and that. And one is left with the question: how does it get there and how does it "know" that it should get there? The answer is that it's just immersed in water and moved about by the unsystematic motion of the water molecules. Some aminoacids go here, some go there. In these animations they only show the ones that end up connecting with the large molecule. OK, this is done just to simplify the visualization, but it can also be misleading.

Similarly with molecules like kinesin, which seem to purposely walk around. Also in that case there's a lot of unsystematic motion, that after a while ends in a particular more stable configuration thanks to electromagnetic forces. Simulations such as this or this give a more realistic picture of these processes.

Don't get me wrong, I'm not saying that the whole thing isn't awe-inspiring or mind blowing. It is. Actually I think that the more realistic picture (without these "purposeful" motions) leads to even more awe, because of the structured complexity that comes out of these unsystematic motions.

They can setup arbitrary rules or ban you without any rules. It’s their service,

Indeed this shows the change in meaning that "service" has undergone in the past 10 or maybe 20 years. Before, the very notion of "service" was that this kind of events could not happen – otherwise it wasn't a "service". Reliability and reliance were integral part of the definition of "service".

Today this word doesn't mean anything anymore.

The title of the post is incorrect. It should be: "Elon Musk rebrands Twitter as the X11 Window System".

Mathematical language is a language, but mathematics is not just a language. It is a structure with internal rules that are not determined by pure convention (as natural languages are). We could internationally agree from tomorrow to call "blue" whatever it's now called "red" and vice versa, but we couldn't agree to say that "2 + 2 = 5", because that would lead to internal inconsistencies (we could agree to use the symbol "5" for 4, but that's a different matter).

This is also related to a staple of science: that scientific and mathematical truth is not determined by a majority vote, but by internal consistency. Indeed modern science started with this very paradigm shift. Quoting Galilei:

But in the natural sciences, whose conclusions are true and necessary and have nothing to do with human will, one must take care not to place oneself in the defense of error; for here a thousand Demostheneses and a thousand Aristotles would be left in the lurch by every mediocre wit who happened to hit upon the truth for himself.

If we want to train an algorithm to infer rules from language, we need to give samples of language where the rules are obeyed strictly (and yet this may not be enough). Otherwise the algorithm will wrongly generalize that the rules aren't strict (in fact it'll just see a bunch of mutually inconsistent examples). Which is what happens with ChatGPT.

Edit: On top of this, Gödel's theorem and other related theorems have shown that mathematical reasoning cannot be reduced to pure symbol manipulation, Hilbert's unfulfilled dream. So one can't infer mathematical reasoning from language patterns. Children learn reasoning not only through language training, but also through behaviour training (this was pointed out by Turing). This is why large language models have intrinsic limitations in what they can achieve and be used for.

My point was that a coffee machine is designed to make coffee, not to keep track of time. Maybe it always takes roughly the same amount of time to make a coffee, and so someone uses it as a proxy stopwatch. But it can very well suddenly take more or less time, without anything being wrong about it – maybe different coffee brands, cleaned pipes, or whatnot.

ChatGPT is an algorithm designed to parrot language, not to perform mathematical reasoning based on logic rules.
