> Can you imagine human potential if it was somehow applied to crop harvesting efficiency, new medicines, etc?

We already have very efficient crop harvesting and Eli Lilly is nearly a $1 Trillion dollar company. Interestingly, the new medicine is designed to keep us from eating so many cheap calories (new weight loss drugs).

> 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 traders and investors who work in this space also go to where they are need, aka where the big money is. So few of these folks are trading corn and soybeans, though some do, rather most are trading drug stocks, tech stocks, and recently sovereign debt related trading (e.g. things like gold and bonds). The focus is around the big questions of our time, like "Are AI investments going to pay off?", or "Is the US going to default/soft default?", and so on.

Deciding how a society allocates its resources, or places its bets, is an important function. Otherwise, you end up with planned economies by disconnected leaders, which often leads to massive failures and large social consequences. Unfortunately, the US is trending in that direction to some degree with it's giant fiscal deficits, tariffs, and tribal politics creeping into economic policy. Nevertheless, traders will weigh these outcomes in their trades, and you'll see a quick reflection from any major change in policy almost immediately, which is a helpful feedback mechanism. For example, the tariff tantrums caused by trump proposing 100%+ china tariffs where he crashed the markets last spring, leading to a moderation in policy.

I think the comment was a roundabout way of saying this is a clear market failure. There are more societally important things these people could be doing instead of shaving another ms off a transaction or finding minuscule option pricing inefficiencies. That the market is not correctly remunerating those options is the failure.

"Akshually traders are good bcuz they crash the market when the president does insane things" is not the own you think it is.

this undervalues how financial engineering allows more ideas and companies to be funded

compound interest is a rare exponential force, and it is available to most citizens of a developed country through the stock market

financial futures remain important for farmers to have predictable pricing, and increase crop yields

science is limited by funding at least as much as it is limited by ideas or intelligence

I understand why finance is a popular bogeyman, but the world is rarely black and white

It’s an important function, but the guys making these bets frequently pull down $10-$100M per year, each. That’s a huge toll to extract from the productive economy for playing this game.

And then there are the guys managing things like pensions, skimming a percentage every year, just because they happen to be locked into that position, meanwhile underperforming a basket of index funds. Just happily eating away at the retirement savings of thousands-millions.

There's no such thing as money being squandered. Money isn't a resource. It's not food, or energy, or even an allotment of work.

If you try to seize or reduce, what you perceive as excess, wasted money supply, that money supply will simply cease to exist.

For some crops we have. But it would be nice to have more diversity, so that the cheapest food options wouldn't be just wheat and corn because they happen to be the crops that are most amenable to mechanized agriculture.
