What if coffee machines were living creatures and existed in a symbiotic relationship with humans? The coffee beans and water would be their actual food and the little thing that the coffee comes out of would, unfortunately, be its peanits. Pissing.

Preprinted! Been working on this for ~1 year w wonderful coauthors Nancy & Mark: > Understanding Artificial Neural Networks: Mysterianism about Known Mechanism is Mysticism doi.org/10.5281/zeno... Have you noticed many experts say they don't understand AI? What's going on? 🤯 Let us tell you... 1/
Understanding Artificial Neural Networks:
Mysterianism about Known Mechanism is Mysticism

Mysterianism is the idea that human cognition, mind, cannot be understood. Taking this
concept and applying it to known mechanism — such that claims are made that we do not
know how engineered systems, such as artificial neural networks (ANNs), work, or that they
constitute black boxes that we can only open with difficulty — is inappropriate at best and
malicious at worst. We do know the mechanistic structure of such models because we designed
and built them. We also do know their functional role (what they are for) as well as the
mathematical function they are asked to approximate (map inputs to target outputs). Because
mysterianist beliefs about known systems, such as ANNs, are often expressed, scientists need
to sit up and take notice. We provide an error theory as to what is going on to help unpick
this metatheoretical blunder. Ultimately, the problem is that ‘understanding’ is not a technical
term in these cases: the word is co-opted for a specific narrative to sell ‘artificial intelligence’
through mystification. All computational systems, from pendulums to databases, will behave
in ways we cannot predict or control — this is not a unique property of ANNs — and experts
do indeed grasp the computational properties of these systems nonetheless.

Three co-occurring (latent) assertions in the context of con-
temporary reasoning on AI and cognition. While they may
appear to hang together in “reflective equilibrium” (Elgin 2017),
their metatheoretical examination brings their contradictions to
light. Starting from the top, and moving clockwise: 𝛼) represents
the typical assertion of so-called cognitive, neural, or otherwise
biological plausibility or inspiration presented for ANNs; 𝛽) is
the claim we tackle head on here — both in terms of analysing
the constituent terms and in how it relates to the other two
assumptions; and 𝛾) exemplifies a type of mysterianism, which
while not always explicitly expressed, plays a background role
and importantly comes into conflict with the other two claims
in important waysMYSTERIANISM ABOUT KNOWN MECHANISM IS MYSTICISM 11World

Figure 3
Not all systems, 𝑆𝑖 relate to their relevant data, 𝐷𝑖 and world
phenomena this way, but ANN models (as many inferential
statistical models) do when used without scientific understand-
ing of the data-generating process or without verbal or formal
theory to match (Guest and Martin 2025b, 2021, 2023). As we
move from left to right above, we move from full understanding
of engineered systems, 𝑆𝑖 to less or even possibly none of the
data, 𝐷𝑖 to the world which can be thought of as the set of
phenomena to be understood.

I honestly don't care if its got an embed fixer on it, if someone posts art in a chat with a twitter link and I want to share it, I'll go find them on bluesky or FA to link it. If I can't find them elsewhere, I just won't share it.

I wasn't able to find a job as project staff since graduating, so I was happy to get a research assistant position recently. But I still somehow won't make nearly enough to cover my expenses. Including tutoring on the side. Why is academia like this.

It's funny that objectively ASS pictures like this bring back the vibes of a vacation better than group photos or selfies. I can't even remember this but I feel it.
A blurry image taken from inside a car, presumably facing outside a side window. There is rain on the pane of glass separating the viewer and the outside, and it is covered in rain. The streaks of rain and blurry nature of the picture create a blend of nighttime colors.

Does anyone else feel like the fact that a recording of music is always the same grounds them? Like, I get to listen to the same performance of Scheherazade today that I heard on Christmas morning in 2017. If we didn't have things like that, I think life would feel like a series of blurry tableaus
