After all, these people could surely be creating something more valuable.
If you want to make an argument based on opportunity cost, it generally should have specific alternatives and a viable cost metric. Without that, it's not an argument, just an opinion.
Now sure you can argue that they were doing only what the society and themselves considered valuable. But one can only wonder if those smart people had been putting their best effort into other things, say developing agriculture or better industrial processes.
I myself did a little day-trading at one period in my life and while I made money, I thought it was the most useless thing I could spend my life in. I was just creating money out of thin air doing basically nothing. Maybe HFT is intellectually more interesting than day-trading but I don't believe it to be very gratifying at deeper level. Perhaps it requires a certain type of person to enjoy that kind of pursuit. I'm definitely not one of those.
Agreed. Modern economics encourages waste, such as multi-level marketing, payday loans, advertising, etc.
Hell, I'm sure most people's jobs here, indeed, most jobs would fall under David Graeber's "Bullshit Jobs".

... I cannot agree. A few years ago I picked up Anthony Kenny's "A Brief History of Western Philosophy", and "A New History of Western Philosophy". What these "useless" debates about knowledge got us were considerable changes in morality, metaphysics, and helped us create things that were useful in the long run. Indeed, the only reason formal 'science' is around is because of those changes in thought and reasoning.
Bertrand Russell has another sort of argument in the same direction, that I quite like. You can find it here: https://books.google.no/books?id=CnlbMP_vBmgC&pg=PA16&dq=use...
> I myself did a little day-trading at one period in my life and while I made money, I thought it was the most useless thing I could spend my life in.
Agreed.
Correct in one sense, but assumes we know in advance what will be waste and what won't be. Central planning has shown itself to be far less effective, both in overall quality of life and in meeting specific demands, than more wasteful competitive economies. So although its easy to point to retrospectively wasteful activities, life without them would be objectively worse.
Tangentially, when covid was in early days and people were beginning to develop vaccines, I saw someone comment asking who was going to coordinate the many disparate development efforts to make sure resources were being effectively used. I can't think of a more starkly absurd idea - it's only by allowing free activity, incentivized by some external, real forcing function, that we can expect to see consistent success. Any central definition and sanction of what should and shouldn't be done instantly distorts incentives towards pleading some central arbiter, and fails.
So all the scuzzy businesses and pursuits that the GP thinks are wasteful, are part of the rich tapestry that overall feeds us and keeps lifting us up. The only way we'd should be signaling they are not helpful is by not using them (and just for greater certainty I'm not talking about tolerating things that are exploitive, harmful, etc, just "wastful")
Right. And through all that thinking about silly stuff, people eventually came to the idea that a LOT of this religion stuff is silly and not worth wasting time on, so smart people could skip worrying about it for the rest of human existence if they chose to. (Whereas beforehand, it was considered a super-important thing to think about).
You seem to imply all this effort was a waste but ultimately it led to the Reformation, various Renaissance periods and, most importantly, Douglas Adams.
I suspect that the same thing will happen with HFT. Either people will stop bothering with it eventually, or they will discover some fantastic new quantum effects that pay dividends for humanity forever more. :)
Brilliant!
What a loss he was, died too young.
And that lead to establishing a whole new field of social sciences that is philosophy. Yes, i am aware that middle-age debates and musings like that were not solely responsible for philosophy as a field of study, we gotta remember eastern philosophers and others too, but they were still monumental to making philosophy what it is today.
Regardless of how much their musings on god contributed to creating philosophy as we know it today in comparison to efforts of others working in that field (e.g., eastern philosophers in old China or middle eastern philosophers of about the same time period), their efforts accomplished a lot in terms of generating actual value for the society through philosophy as a field of study. Unless you are dismissing the entire field of philosophy as it stands today as "useless", then the value of those discussions is pretty obvious.
Not even mentioning second-order effects, like those debates making people question prior assumptions and embarking on important scientific endeavors, like trying to prove that Earth might be indeed revolving around the sun and not the other way around.
Just wanted to highlight that specific time period, since it was pointed out by the parent comment as a specific example of those efforts going nowhere.
Most systems are pretty inefficient and the problem is at the time we do not know which pursuits will yield the most valuable results.
Top-down, authoritarian direction of intellectual pursuit tends to yield worse outcomes than just letting people do as they wish. It's dangerous to suggest that any single perspective can accurately decide value.
Taking it from less skilled traders, actually.
HFT is automated day-trading in a way, so 1 meta level more intellectually interesting I suppose.

What is the argument against Arbitrage having a lag of even, say, 90 seconds?
And like... who cares about the price delta on a time scale even less than an hour apart from day traders? FX stuff I guess?
The effects of HFTs aren't limited to HFT vs traditional traders. Their artificial arbitrage affects people's retirement funds and the like. It wouldn't be so bad if they were just making money off other traders but instead they're making money off everyone with money in the markets.
Huh? It's narrowing bid-ask spreads, which is beneficial to other market actors. There's nothing "artificial" in it other than betting that the price fundamentals won't move against them, like any other market maker.
Not true. The HFTs are often market makers and are PAID to be in the market by the exchanges at all times so that others have something to trade.
I believe that arbitrage within the platform kept the prices and exchange rates consistent (i.e. it didn't matter whether you bought Bitcoin for EUR or first changed the EUR to USD then used that to buy Bitcoin), but of course you could make/lose some money by exchanging EUR <--> USD on the platform then exchanging it back outside (or simply exchanging it on the platform, waiting until arbitragers brought the exchange rate back to normal levels, then exchanging it back).
But in effect, the lack of efficient arbitrage between the platform and the "real world" that allowed EURUSD rates to drift so far meant that how much your coins were worth depended on what currency you bought/sold them for, making the whole thing highly annoying.
The cryptocurrency markets, which seem less mature/complicated/HFT-overrun than the "big" markets, are great for learning market principles.
If every trade settled at, say, the rolling average price of the last 60 seconds-- or 60 minutes-- it would dramatically quiet the "noise" in the market. There would still be enough demand from conventional investors, and the averaging policy could actually stabilize the riskiest scenarios (i. e. a temporary loss of market makers causing orders to settle at comically out-of-bound prices)
Any other method to force a uniform price, i.e. a price that cannot quickly change in response to information, creates arbitrage opportunities that are greatly unfavorable to retail investors.
