This comment is wild :) In Europe we send our best athletes into athletics, not sport. Athletics is track and field, which reduces to speed, strength and endurance. Sport - football, cricket, tennis - is about technical mastery first, and only secondarily the speed strength and endurance to support it. Lionel Messi and Sachin Tendulkar would both have been deselected by any athletic selection procedure. The emphasis on athleticism over technical mastery is what makes American sport boring.

Sounds like desk strat RAD work is moving to LLM gen code at JS. My recentish experience of that kind of work has been Athena at JPMC and Quartz at BoA; both Python with functional style via DAG or pixie with py ui framework to match. Which enables quick dev of the parts of trading workflow that don't need to be quick, like booking tools or EOD risk. I know first hand Athena and Qz are crufty when you get into the weeds. The bonsai framework with Elm inspired ocaml impl sounds v cool. So I can see how this approach can accelerate a lot of trading tech dev. But does it have any traction over the hard problems where we turn to C++ or Rust: near real pricing and risk across multiple instruments and markets?

Is C++ the most heavily documented programming language? If so, these docs could form the most detailed description of a subset of possible software ontologies for Von Neumann architectures. By possible software ontologies, I mean the debate around OOP, DOD ArrOfStruct vs StructOfArr, out of bounds and mem safety, GC vs manual mem mgmt, atomic types vs arrays vs objects and their layout in memory, function dispatch mechanisms, genericity mechanisms etc.

Strongly agree from an Emscripten C++ wasm pov: it's key to minimise emscripten::val roundtrips. Caches must be designed for rectilinear data geometry, and SharedArrayBuffers are the way for bulk data. But only JS allows us to express asynchrony, so we need an on_completion callback design at the lang boundary.

By "procession", do you allude to the filioque clause? Agreed on difficulty of translation as I follow Quine so think a language as a whole is the unit of meaning as opposed to any specific granular element.

Allusive and romantic. My view is to see data as geometry, not poetry. Rectilinear data is cache friendly.

Love the Freak Brothers references; two US counter cultures that do cross pollinate. Z80MC RAM & ROM seem v generous compared to the ZX81 I used to cut my asm teeth, wobbly RAM pack and all...

Also UK style outsourcing eg Capita, Serco and recently Tata Consultancy Services fubaring JLRs infra.

Sounds positively monastic, in the best way. Your magnum opus rendered as glorious coding codex is surely preordained. I'm reminded off Cyril Connolly's Pram in the Hallway. We are all prisoners of our brain chemistry.

Yes, completely agree. LLMs instantiate Searle's Chinese Room argument; symbols alone have no meaning. And yes, I buy the Kripkenstein argument. The meaning is the use, and intersubjectivity is key. My fear is that the humans who should know the use are having their grasp on that use degraded by production and consumption of AI slop text. Understanding requires application, and AI slop is letting the lazy off that hook.

I'm guessing Swiss Bank/UBS as a mate used to trade there and had a NeXT workstation and loved Wingz. Later I heard they were doing server side pricing work on Apple servers. I stand corrected; thanks!
