This is an excellent report on why full RSI / an intelligence explosion is fighting diminishing returns on many fronts, and not yet showing signs of happening. Really recommend reading. I wish I wrote it. While I agree with it, it could end up being wrong! www.noahpinion.blog/p/wheres-the...

Is all code becoming the same? On one hand, 95% of Kaggle submissions that set a random seed now use 42 (a Hitchhiker's Guide joke LLMs love). But, it turns out that while coding syntax is converging, approaches to problems are not converging. Human prompters drive real variety in solutions.

today we had a nice discussion on q: 'does Sutton's Bitter Lesson apply to neuroscience?' Sutton argued that big compute and data lead to AI systems better than any human-crafted alternatives. Neuroscience has big data now, is it going the same way? Eg www.nature.com/articles/s41...
Photo of a happy-looking Rich SuttonFigure 1a from Lappalainen et al 2024, shows schematic diagram of their strategy to train a recurrent ANN with connectivity constrained by fly optic lobe connectome, then compare it to actual fly brain activities.“The biggest lesson that can be read from 70 years of AI research is that general methods that leverage computation are ultimately the most effective, and by a large margin.”
“The bitter lesson is based on the historical observations that
1) AI researchers have often tried to build knowledge into their agents
2) this always helps in the short term, and is personally satisfying to the researcher, but
3) in the long run it plateaus and even inhibits further progress, and
4) breakthrough progress eventually arrives by an opposing approach based on scaling computation by search and learning.”The goal of neuroscience is to understand the brain.
But what if we humans are just not smart enough?
Neuroscience is entering the big-data era:
Connectomics (brain wiring)
Cell types census (brain parts catalogue)
Large-scale neural activity recording methods
Spatial transcriptomics (molecular expression)
Should we just combine all this data with machine learning, do a big brain simulation, then go home?

I spent so many hours working through papers like this only for the field to switch to the 'neural network go brrr' paradigm
Lemma 2 Suppose B is a CIS and h a surjective CIS homomorphism from
P(Σ∗) → B. Then let G be a context-free grammar. Let φ be the cfg-
morphism given by φ(N) = h(L(G,N)). Then for all nonterminals N in G,
L(φ(G),φ(N)) ⊆h∗(φ(N))
Proof We will assume for clarity of exposition that the grammar is in CNF –
the proof of the more general case is straightforward but less legible.
Suppose we have a rule N →PQin G. Therefore L(G,N) ⊇L(G,P)L(G,Q).
So h(L(G,N)) ≥h(L(G,P))◦h(L(G,Q)).
Then h∗(h(L(G,N))) ≥h∗(h(L(G,P))◦h(L(G,Q))) by monotonicity of
h∗. By Proposition 39 h∗(h(L(G,N))) ≥ h∗(h(L(G,P)))◦h∗(h(L(G,Q))).
Similarly suppose we have a rule N →a in G. So h(L(G,N)) ≥h({a}), and
h∗(h((L(G,N))) ≥h∗(h({a})).
Now suppose that N′ ∗
⇒φ(G) w; we want to show that w∈h∗(N′). We pro-
ceed by induction on the length of the derivation. Base case: the production is
of length 1. Suppose N′→ais a production in φ(G). Then for any production
N →a in G such that N′
= φ(N), h∗(h((L(G,N))) ≥h∗(h({a})) ≥{a}.
Suppose it is true for all derivations of length at most k, and let N′ ∗
⇒φ(G) w
be a derivation of length k+ 1 that starts with N′→P′Q′→uv= w, where
P′ ∗
⇒φ(G) u and Q′ ∗
⇒φ(G) v. these last two derivations must be of length at
most k.
Then consider any production N → PQ in G such that φ(N) = N′
,
φ(P) = P′ and φ(Q) = Q′ (of which there must be at least one). Now by
the inductive hypothesis, u∈h∗(P′) and v∈h∗(Q′). So uv∈h∗(P′)h∗(Q′) =
h∗(h(L(G,P)))◦h∗(h(L(G,Q))). Now since h∗(h(L(G,N))) ≥h∗(h(L(G,P)))◦
h∗(h(L(G,Q))) this means that uv ∈h∗(h(L(G,N))). So w ∈h∗(φ(N). By
induction, it is therefore true for derivations of any length.

My article 'Constitutive Self-Consciousness' is now published online in the Australasian Journal of Philosophy. It argues (spoiler alert!) against the claim that self-consciousness is constitutive of consciousness.
The claim that consciousness constitutively involves self-consciousness has a long philosophical history, and has received renewed support in recent years. My aim in this paper is to argue that this surprisingly enduring idea is misleading at best, and insufficiently supported at worst. I start by offering an elucidatory account of consciousness, and outlining a number of foundational claims that plausibly follow from it. I subsequently distinguish two notions of self-consciousness: consciousness of oneself and consciousness of one’s experience. While ‘self-consciousness’ is often taken to refer to the former notion, the most common variant of the constitutive claim, on which I focus here, targets the latter. This claim can be further interpreted in two ways: on a deflationary reading, it falls within the scope of foundational claims about consciousness, while on an inflationary reading, it points to determinate aspects of phenomenology that are not acknowledged by the foundational claims as being aspects of all conscious mental states. I argue that the deflationary reading of the constitutive claim is plausible, but should be formulated without using a term as polysemous and suggestive as ‘self-consciousness’; by contrast, the inflationary reading is not adequately supported, and ultimately rests on contentious intuitions about phenomenology. I conclude that we should abandon the idea that self-consciousness is constitutive of consciousness.
