A while ago I was having a discussion, and someone asserted that synthetic fertilizers are necessary because composting doesn't scale.
And my reaction was, surely composting scales to an entire biosphere - like, empirically we know this, right? There was a massive biosphere long before there was a Fritz Haber. Surely it's that we don't have the required technology and wisdom to create supply chains that can run as closed loops and accept inputs that aren't so rich and concentrated?
I don't want to argue this point, there are definitely good counterarguments that could be made, but I'm just trying to illustrate the shift in perspective I think the commenter may have been going for rather than change the topic.
I still think it's doable (but not if we also want to feed many times our mass in lifestock), but it's not easy.
What got you here might not get you there. You can go really far with a monolithic web app running on top of a relational database. But if you scale far enough, you'll need to pull some pieces out and hook them up to databases with relaxed constraints.
There are good engineering reasons for us to do things the way we do them, and maybe it was the only feasible way for us to get to this point. But presumably if we continue to grow, we will enter a different phase with a different set of tradeoffs. That phase will probably involve exerting less control, it will probably also involve worse unit economics, but may also scale further with fewer externalities.
By definition, yes.
> There was a massive biosphere long before there was a Fritz Haber.
There are about five times more humans today than there were when Fritz Haber invented his process.
The question is not “will there be an ecosystem”. Of course there will be. The question is are you ok with 4 out of 5 person potentially starving to death.
> Surely it's that we don't have the required technology and wisdom…
Synthetic fertilizers is the required technology and accepting that is the wisdom.
Again, I don't want to get into a debate about agriculture, I'm trying to discuss the quote, but these are the types of assumptions I'm suggesting are worth questioning.
The question is, are there ways to exert less control and get better outcomes? I'm not suggesting we let 80% of people starve. I'm suggesting we not be obsequious to the logic of the technology we've already built, when deciding on what to build next. (I elaborate in a cousin comment.)
Consider that in the extreme, if you have a linear supply chain with Haber-Bosch on one end and a landfill on the other - when you scale to enough people, you will also have mass starvation. Haber-Bosch isn't a "wisdom we accept" or "the" definitive technology. It has tremendous application, but it isn't magic. We're not simply done innovating in this area.
Would you say the same about great works of fiction, or old fairy tales that for some reason keep grabbing our attention and we repeat them for generations? That they're just falsehoods because duh, frogs obviously can't talk? Or can they have some deeper meaning? Stating facts is not the only way to describe the world.
Do you thing religious followers, such as Matthew, see god/heaven/etc as being merely a metaphor?
> That they're just falsehoods because duh
per previous poster: "laws and government don’t tell you how the world works"
works of fiction doesn't purport to either. They might have morals, or subtexts, as much of the contents of the Bible does - but some things in there are meant to be at least partially literal, such as the existence of a divine being that created the world.
What's the greater message behind "God takes care of lesser creatures" when there's no proof of such a thing? That things will generally turn out alright if you don't plan ahead (demonstratably bad advice)..
No, I'm not suggesting that. The alternatives to just reporting facts are more than "merely a metaphor".
> works of fiction doesn't purport to either. They might have morals, or subtexts
Disagree - I think they distill patterns from the factual and present them in the form of stories, encoded in the structure of the story. If you're a materialist you might say that the story is less true than the factual manifestations of the patterns, I'd say it's more true; and that it's telling something about the world.
> What's the greater message
We're debating if zero even exists, don't ask me about analysis ;)
It’s a medieval gaslightenment and it would be great if people kept it private at least.
PS. purpose is different from meaning, the latter is just a medium for purpose and may be arbitrary.
I think it's a misguided sentiment of its time, we know today that birds also bust ass in their own birdy ways to live. We all bust ass.
