Have you heard the thought that LLM hallucinations when coding within an API / framework are feature requests against the same?

I have a suspicion that Julia, owing to multiple dispatch, has a sort of regularity that makes that you said plausible.

Though there is just so much more Python to train on, any I bet they even do RL with validated rewards on Python, and probably not Julia.

Woodworking is, like, the quintessential craft. I think it is very useful to bring it in when discussion "craft"!

I am not myself a woodworker, however I have understood that part of what makes it "crafty" is that the woodworker reads grain, adjusts cuts, and accepts that each board is different.

We can try to contrast that to whatever Ikea does with wood and mass production of furniture. I would bet that variation in materials is "noise" that the mass production process is made to "reject" (be insensitive to / be robust to).

But could we imagine an automated woodworking system that takes into account material variation, like wood grain, not in an aggregate sense (like I'm painting Ikea to do), but in an individual sense? That system would be making judgements that are woodworker-like.

The craft lives on. The system is informed by the judgement of the woodworker, and the craftperson enters an apprenticeship role for the automation... perhaps...

Until you can do RL on the outcome of the furniture. But you still need craft in designing the reward function.

Perhaps.

> Intel's first 32-bit microprocessor was the iAPX 432, which was introduced in 1981, but was not a commercial success. It had an advanced capability-based object-oriented architecture, but poor performance compared to contemporary architectures such as Intel's own 80286 (introduced 1982), which was almost four times as fast on typical benchmark tests.

I know that there was OO hype, but 1981 seems kind of early. I also know that OO means many, many things. What does it mean here, if anything?

Are the 50 for loops truly necessary in the manual C code example of a Kalman filter? At least introduce a few functions (that could be inlined and loop-fused) for some matrix operations?

Another way to make the same point is to observe that every single society has language.

But only some groups have the ability to systematically encode language as writing.

Writing is a technological marvel.

This is the first time I see "SGD" to mean "standard gradient descent" and not "stochastic gradient descent".

We're not using "type theory" the same way, I think. I'm thinking in terms of

    - simply typed lambda calculus
    - System F
    - dependent type theory (MLTT)
    - linear types
    - row types
    - and so on

But it's subtle to talk about. It's not like there is a single type theory that underlies Typescript or Rust, either. These practical languages have partial, (and somewhat post-hoc) formalizations of their systems.

> people who like type systems tend to dislike Julia's type system.

This is true. As far as I understand it, there is not a type theory basis for Julia's design (type theory seems to have little to say about subtyping type lattices). Relatedly, another comment mentioned that Julia needs sum types.

I think of context parameters as a replacement for dynamic scoping.

I think it can be all of these things, which in my opinion partially undermines the GP's point.

Also, statefullness. Baudot has two codes used for switching into one of two modes: figures and letters.

Typewriters have some statefullness, too, like "shift lock". Baudot needed to encode the actions of a type writer to control it, not the output.

A search for "LLM Harry Potter" would suggest that LLMs are widely understood to be proficient at rote memorization.

(I find the example of the computational geometry algorithm being a clear case of direct memorization not very compelling, in any case.)
