Not sure I quite buy this comparison with NAND. As NAND truly does let you represent any Boolean function (I think). Whereas this will have gaps for non-elementary functions.

arxiv.org/html/2603.21... New preprint appears to show that lots of key functions and constants can be reduced to some series of call to a single primitive function: eml(x, y) = exp(x) - ln(y) One it is cool and two possibly useful for symbolic regression and recovering equations from ML. 🧪🤖

Yes, I wouldn't say humans do it better. automated search could reduce biases from humans. But we need to make sure we don't slide into other biases instead. I think the power of llms to process large amounts of text rapidly is useful and needs to be applied carefully.

Matishalin @matishalin.bsky.social · 05/04/2026
There is a good way to include llms in a research pipeline but trying to automate everything via bootstrapping is not it!

Matishalin @matishalin.bsky.social · 05/04/2026
Beyond biases in the llm models themselves. Naively using llm generated skills or just poorly thought out ones will only make it worse!

There is an explicit bias to find authors at prestigious universities and senior positions. This will lead to a very clear western, male, white bias in any literature searches with this skill.

Some of the issues here: The timelines and citation counts are field dependent. This will lead to some fields getting weird answers on what is foundational (whatever that means).

Toxic people failing upwards: Universities must do better
Today* I am angry. Yet another person I know who exhibits toxic behaviour in the workplace has been ‘failed upwards’. This is a well known phenomenon whereby individuals are not sacked for poor behaviour, but rise through the ranks of higher education. Taking their (often appalling) behaviour with them to a new institution, usually with a hefty salary and title bump to go with it.

They are sequential hemaphrodites! All born male and when they inherit an anemone they develop into females. Each group has a dominant female, a smaller breeding male and a queue of progressively smaller underdeveloped males helpers. Such a cool system! en.wikipedia.org/wiki/Orange_...

yes more acc the branch of middle english leading to english. old-english used a partative genitive (i think; I am only a hobby linguist). I think the key point is zero was introduced and naturally replaces "no" or the indication of an absence of stuff, so takes a partative construction.

Matishalin @matishalin.bsky.social · 04/03/2025
At least that's my understanding! But I haven't opened a linguistics book in 10 years so could be wrong!
2110
Matishalin @matishalin.bsky.social · 04/03/2025
The branch leading to English used to have a dual class (two things only) so it's not unreasonable language may develop a null class of grammatical number some day.

Matishalin @matishalin.bsky.social · 04/03/2025
Lots of confusion here. It's not about singular/plural. Zero came after English grammar stabilised, we used the partative for no things: I have no marbles. English partative looks like the plural sometimes. So it's confusing ppl.
