With a huge pile of salt

> In July 2025, the Securities and Exchange Board of India (SEBI) alleged that Jane Street used multiple entities for market manipulation and barred it from accessing the market.

As I understand Jane Street they have done great things for OCaml and they also do their own web framework (I guess that big money bin needs a lot of dashboards).

I think the designer here takes a wrong approach and sort of falls into engineer envy where he wants to make prototypes as deep and realistic as possible. And that is not really the most important part of the design job.

The most important thing is that the right thing gets build (why do we need a JSQL input box? what do we actually want? what are other ways to do this?). And this is often better done with pen and paper sketches, meetings, observation, discussions ... rather than too quickly narrowing on a particular design and spinning into discussions on whether buttons should be on the left or on the right, LLM intricacies etc.

Even if they're not, I'm not sure if we should care a quantitative trading firm's opinions on frontend design...

The whole HN is one huge AI ad now.

Maybe a random employees mildly interesting blog post is not exactly where we need to look for a psyop. But that is maybe what they want you to think.

Gotta pump those numbers up. Those are rookie numbers in this racket.

I myself, I pump my investments at least twice a day. Once in the morning, right after I work out. And then once right after lunch.

I want to, that's not why I do it. I do it cause I fuckin' need to.

Most are. Some are paid for.

I'm not saying AI isn't a good tool. However the less you understand what you're using and what you're doing the further you stand to geopardize the business you're working for.

This is why hn is the best. First comment helps to decide if we need to read the article or not .
