China has to hoard food and grain…a population like theirs within such a large country that doesn’t have enough arable land to support itself…they can’t risk starvation.

Sorry, I was paraphrasing from a talk I attended last week (I'm an economic geologist), but I don't have the data handy.

Suffice to say, most people in the industry don't have high hopes for our metal output in the next couple of decades. Nuclear is really our only hope imo.

Are entire populations going to upload their consciousness to the cloud? Because until that's possible, wherever their feet are firmly planted on the ground is where their State is, regardless of what online networks they decide to be active with.

This just looks to me like crypto bros trying to make a comune... It doesnt sound realistic, feasible or desirable, but im sure someone will try to force it for clout... To be a real thing, it would definitely need more than 10 years...

Do you have any links I can read more about this? Thanks.

OK, I've read the thing. I don't think this is going to work. The REE's are going to have to rise to a really high level before this is economical.

>The authors found that an uncharacterized new species of Nostoc had the highest capacity for biosorption of ions of these four REEs from aqueous solutions, with efficiencies between 84.2 and 91.5 mg per g biomass, while Scytonema hyalinum had the lowest efficiency at 15.5 to 21.2 mg per g.

So from the start there's not a lot of good yields to begin with. Higher than parts per million, but seeing as its REE, no surprises there.

>Also efficient were Synechococcus elongates, Desmonostoc muscorum, Calothrix brevissima, and an uncharacterized new species of Komarekiella. Biosorption was found to depend strongly on acidity: it was highest at a pH of between five and six, and decreased steadily in more acid solutions.

Due to several aspects of minerals, how they mine things, and the sulfur inside the rocks, most of the mining tailings are acidic instead of alkaline. In other words, if you want the higher levels of biosorption, you're going to have to chemically treat the tailings before you can get them. In fact, there's a whole spectrum of acidities and alkalinities that they're going to be using. Meaning this process probably fails.

>The process was most efficient when there was no "competition" for the biosorption surface on the cyanobacteria biomass from positive ions of other, non-REE metals such as zinc, lead, nickel, or aluminum.

Have these guys ever looked into a mine tailing or factory waste? It's chock full of random non-REE metal ions. This means that yeah, you're going to have to extract and flter that mine tailing before you can get the REEs efficiently.

The only reason why bioremediation and biosorption of the waste is loved so much is because bacteria are self-replicating and frankly don't really give a shit if you throw them into a toxic dump. They're still happy to turn those heavy metals into less dangerous types or break down cyanide or absorb the cadmium into their chitin structure. Other forms of cleanup have problems due to how spread out things are and how large the volume of water is. But if you're trying to run a business that involves extracting the stuff for money, that means you have to pre-treat the stuff before it gets to you, usually chemically. And that costs a lot.

Submission Statement: What barriers are there for network states growing? What are some ideals that network states might even be organized around? Is this a realistic way that humans might coordinate as a people in our future?

Why saying US is evil means saying Russia is good? Both search their own benefit. In some ways Russia is worse than US and in others US is worse than Russia.

For the first question: yes.

The issue is this isn't the same concept as mosquito efforts where genetically modified mosquitos are released and meant to replace the natural populations. So we won't be ridding the world of disease-causing bacteria ever.

This isn't practical for bacteria. There are several limitations that these mosquito effort don't have(one obvious one is bacteria aren't buzzing around us for us to easily detect haha)

For the second question: Bacterial conjugation (genetic transfer between bacteria via direct contact) is definitely a possibility for certain bacteria with these capabilities. Also, it is typically plasmid DNA (so DNA from a tiny "chromosome" versus the main bacterial DNA) so these genes would have to be on this plasmid to be transferred typically, and it is likely not a part of this DNA, but who knows (I haven't looked into this bacterium). However, it isn't like a domino effect or a wave where these genes transfer exponentially. So if this did occur, it would likely remain a significant minority of the bacteria (like 0.0001%) because these would likely be engineered at a massive scale to perform the function. I also doubt where/when this occurs there will be a significant natural population of these bacteria. If there is, they could/would likely be killed before repopulation begins.

I haven't looked into this exact use so I don't know how they are planning to go about everything so my comment might be missing some key information.

Basically, these things are easily accounted for with bacteria (with some exceptions depending on the bacterium).

Right now they're all like Paramount+: no one has them, no one gives a shit. There's going to come a day where they're going to have to do some kind of cash for clunkers type buyback program or something. But again, going back to my original point, US auto emissions are a drop in the bucket compared to the waste that corporations in China and elsewhere get away with dumping.

How does anything I said make the US the good guys? It’s irrelevant to my post about long term resource scarcity planning. If anything it makes the US the bad guys lol.
