    Neural networks don't work as well as some specific algorithms for specific problems, but they are great generalists, so you can throw a NN at almost any problem and get at least OK results. Just like humans vs. machines, we have machines that can do things faster than us, more accurate than us, and more reliably than us, but they can't also run around a field and kick a ball and climb a tree and swim.

    The people who are completely rewriting their SSD every single day are generally the ones who know how to replace their SSD. If you, for instance, completely rewrite 5GB/day (which is on the way-up-there high end for somebody who browses and uses Office) on one of the small 64GB SSDs you have over 80 years before failure. The great thing about SSDs is that they don't wear out from reads like spinning rust, only from writes, which means that for typical use cases they have much higher life expectancy. Hell, even at 20GB/day a 64GB will last 20 years, and who still uses HDDs from 1992? Add to that, they have hardware compression, so those blocks that your OS thinks are taken up with a 20 byte file aren't actually taking up space at all, leaving extra room for wear levelling.

    They do write-leveling, so you have to completely rewrite your entire SSD every single day for 8 years if you want to start getting close to the 3k write limit. In 8 years we'll have SSDs for less than 1/10th the price, and replacing them will be cheap.

    This is South Africa I'm talking about, not the jungle. We have all of the economies of scale that you're ever going to benefit from with tomato sauce. We have industrial fruit picking machines, 18 wheeler transportation, mechanised bottling, local glass jar moulding facilities, large cold-storage facilities, the works. We export huge quantities of fruit (particularly apples and oranges) to both the EU and the US, so I don't expect the Italians to have better environmental conditions or they would be exporting their own fruit and undercutting us. We export a lot of wine which is competitive with (and often undercuts) the rest of the world, so I don't see how our tomato situation would be so different.

    Apparently Italians use migrant labour, so they're about even on that. But they're still down on shipping. They get around this by getting the EU to subsidize their tomato exports - here's an article from Australia complaining about the Italian canned tomatoes putting the locals out of business:

    From the time I've spent there, and the friends attempting to start businesses there, I have to agree with that analysis. I would add, however, that the police are still very heavily armed: a typical roadblock for checking licenses will typically have two police with AK47s. There is a lot of low-level corruption - particularly police - which needs to be stamped out as the country becomes stronger if their democracy is going to survive.

    Occam's razor indeed.

    You're saying that:

    A large conglomeration of green energy companies wanted to block competitors so they hired a bunch of lawyers who looked through arcane lawbooks and found a little used law that said they could block their competitor by getting the president to make a personal declaration against it

    Paranoid US security forces were more than a bit nervous when they discovered that the big towers going up near their top secret testing location were owned by a nation which is involved in numerous cases of industrial and military espionage.

    Hate to say it, but the official version sounds more plausible.

    Ah, yes, absolutely. And even without the subsidies, competing with Big Agri is hard enough for the little guy when customers are very conscious of the price they are paying for food, and aren't very fussy about it being "organic" or "local".

    As for the subsidies, as an example, I know it's cheaper here to get Italian tomato sauce than local, which makes absolutely no sense. The only way for that to be possible, given wage disparity and shipping costs, is for the Italians to be selling their sauce for below cost. Anything to get their trade deficit down, I guess.

    Interesting how, from your point of view as a white European, I'm so very very wrong. I live in Africa, so I think I'm a bit more qualified on this topic than you are. And no, I never said anything about a surplus. But there's no incentive for a farmer to plant if he knows that he'll have to compete with 'free' by the time his crop is ready for harvest. For example, in Mozambique the UN-donated flour is a staple, meaning that it's almost impossible to locally produce any carbohydrate food source because it isn't profitable. People are poor, and they're not going to pay for food when there is a free alternative.

    How the hell are sanctions going to help with disease, no tarred roads and no houses? What really needs to happen is the EU/US needs to export skills and education, while ensuring the children they're teaching are properly fed and have the infrastructure to use their newly acquired skills. Ever tried learning on an empty stomach? Ever tried doing IT when your electricity is unreliable? Ever tried delivering perishable food when there aren't reliable roads? How useful would your skills be in a rural village in Uganda?

    What the Chinese are doing is using local labour with Chinese foremen to build roads and bridges, but that's just so that they can extract as much mineral-wealth as efficiently as possible. Any positive change they're making in the region is just a lucky side effect.

    Maybe robotic farmers.....maybe they could figure how to feed themselves for a change....

    You realise one of the reasons Africa has famine is because westerners keep dumping free food on them, putting the local farmers out of business? It's a bit of a vicious cycle - you can't just ignore millions of starving people - but every time free food gets given out it upsets market prices as well.

    It's a bit like the H1B situation in the states keeping skilled professionals' wages low.

    Unfortunately, protein isn't the only necessary component. Stimulus is also pretty important.

    The only protein which would be lacking from a (western) vegan diet is lysine, which, funnily enough, is very prevalent in beans and lentils. It's also there in our regular carb sources (wheat, oats etc) although in small quantities, which means you would need to do a ton of exercise to burn off the calories in grains that you'd need to eat to get sufficient lysine. Interestingly, Formula1 drivers are, for the most part, vegans.
