Isn't Jane Street mostly into HFT arbitrage?

You need market makers like Jane Street to have well functioning markets. The markets have shown themselves to be an excellent way of applying human potential to things like crop harvesting efficiency, new medicines.

Markets existed before HFTs, they will exist without them as well.

All I think when I see this is "this intelligence wasted on finance and ads." Can you imagine human potential if it was somehow applied to crop harvesting efficiency, new medicines, etc? Not everything has to be perfectly efficient but it just saddens me to see all these great minds doing what, adversarially harvesting margin from the works of others?

The smartest people are going from Harvard et.al. into finance, adtech, investment banking, wallstreet.

What they could achieve in spending their attention on real problem would be massive.

As someone who has worked in the industry, I've yet to see any compelling argument that high frequency quants are making any meaningful contribution to society. Maybe on the low frequency end, but slightly higher market liquidity doesn't serve that large a social good imo.

High frequency quants almost certainly don't directly provide a massive social good, but they're one of the many facilitators enabling the smooth functioning of markets that do. But FWIW, the comment I was replying didn't seem to be specifically critical of high frequency quants. Dismissing the entire field as something that doesn't contribute to society is beyond absurd.

I didn’t read the OP as being entirely dismissive, but rather making a point about relative impact.

You could make the case that a neurosurgeon is contributing to the field by being a full-time reviewer of a research journal; like a quant, they are providing utility by assisting in the flow of information. But I suspect there are many people like me who think they would have a bigger impact by putting on scrubs and working in an operating room.

Don't we already harvest more food than humans could ever eat, and have a huge pharmaceutical industry? I get what you're saying but these two examples seem counterproductive imho. Which begs the question: what would actually be a good field to apply human potential towards? I agree that finance, sales and ads are very low on that list.

It’s been a few years since I looked deeply into it, but I think we produce enough to have everyone survive but not necessarily thrive. At the time, it came out to something like 1700 kcal per person. Even if we did have enough, the next problem is logistics of allocating that food to everyone who needs it.

If markets were regulated to trade in coordinated 1s auctions, instead of nanosecond precision first-come-first-served matching of orders, markets would function just as well without needing a ton of what the HFT crowd does. It's a massive waste of brilliant minds.

If these sectors offered competitive salaries - sure, talent would flock to them. As a former chemist, I struggled to find a job that didn't pay scraps, no matter the industry - from big pharma to advanced materials. Eventually, I just gave up and went into the IT, which is 3x-10x better paid (at the very least).

We let the market dictate how society's resources are allocated. And we see, as a result, how the market is actually not at all interested in the satisfaction and well-being of the people in society.

Yeah I saw something fly by on my feed that they were responsible for big btc dumps https://x.com/1914ad/status/2026757796390449382 Haven't read it yet but seems spicey

Multiple cases of market manipulation. It's a super shady operation
