While the pharmaceutical industry is large, the marginal researcher does still seem to have a pretty positive impact from an outside view.
The most positive use of human time probably looks something like antiwar advocacy, but I don't really think that most quants have the social skills for that tbh.
I have good news and bad news for you. Good news: we've known the solution to that for more than a century, which is to reduce livestock consumption, a cause which many smart people have dedicated their lives pushing vegetarian/vegan culture and producing alternatives. Bad news: from my point of view, the masses are not going to give up meat and eggs faster with each additional alternative meat.
> each additional alternative meat
As a side note, for many vegetarians and vegans, “alternative meats” actually mean hundreds of different legumes (fresh, dried, milled, split, fermented…) and other delicious plant foods. They’re packed with macro and micronutrients that can replace[0] those found in meat.
Taste is a bit trickier: nothing will ever taste more like flesh than… flesh — and taste is subjective anyway. Meat substitutes can be tasty, but they’re not the same. Which brings me to this:
the masses are not going to give up meat and eggs
That’s true. At first, giving up meat just to eat “fake meat” can feel like a downgrade. But the real key to change is curiosity. There are so many ingredients and recipes to explore. Classic egg-and-milk pancakes are great — but why eat the same thing all the time when there are so many combinations of plant milks and oils to try? I used to love pig and chicken. Now my favorite staples are fried tempeh and lentils with nutritional yeast.
0: I like to joke that meat replace beans, you get the idea. Fun fact: meat is viande in French, from latin vivenda which mean "which sustains life" and used to describe any edible. I think english meat have a similar etymology from mete.
From this outsider's point of view it's failed to have a positive impact; people nowadays are far less healthy and happy than they were half a century ago when the pharmaceutical industry barely existed.
Just look at what happened when AI took off in the US and our ongoing struggle to get global warming under control - only China is taking a serious stab at this which is why they’re absorbing AI more effectively than we are.
Also semiconductor manufacturing has clearly gotten way too concentrated and there’s not enough experimentation with new designs (eg throwing more at existing DRAM designs instead of building new designs like in-RAM compute to shift the power and performance by an order of magnitude or 2 thereby easing the pressure of how much is built).
But as you pointed out, this is not the actual issue. Getting food to people who need it is almost entirely a political and logistical issue at this point. War (especially civil war), natural disaster, with local power stealing international aid, etc, are mostly the biggest responsible for hunger in the 21' century. We have the technology and logistics to accurately drop-ship huge amount of food in even the most remote places in the world, even when the local infrastructure is heavily damaged or inexistent. We cannot deal with local power decision to voluntarily starve a place.
The average per capita is closer to 2,600 kcal/day. Not sure how that breaks down when normalized by the individual country population. It also doesn't include waste. In the US at least, waste is near 40%.
