  • but that we should feed people and also improve conditions for livestock.

    Actually, this basically was my point - to acknowledge that most people would object to being fed the way the animals they eat are fed (and also housed, and otherwise cared for) but it’s also important to recognize that the problem is not as simple as simply changing what crops are grown for what purpose. Land used to grow feedstock is not necessarily suitable for growing food that humans eat, and beyond that there’s a massive infrastructure issue (storage and transportation of bulk crops like alfalfa is a lot simpler than, say, tomatoes or bell peppers or apples).

    Why did you assume my previous comment was malicious? is that your default reaction?




  • There was no period without warfare or economic stability in Palestine.

    I mean… there was time to build a bunch of modern residential buildings, hospitals and businesses (the things Israel is currently blowing up and bulldozing) and for people to live their lives without having to be armed 24/7. It literally has not been open warfare (at least for a little while), and yes there was some economic stability, enough for local Palestinian businesses to develop, for a semi-functional civilian government to form, and for civil services like hospitals and schools to be established. It hasn’t just been a warzone for 100 years.


  • QR codes are just symbols in a camera readible way and barcodes numbers in a camara readible way.
    A storage medium for 0´s & 1´s like a USB stick or a disc but way less storage.

    Yes, a QR code is a representation of digital data. There are different versions which can represent different amounts of data. The represented data can be anything that you want, as long as the scanning device can interpret that data as something useful.

    They dont add any security,

    An RFID tag holding a blockchain token string also does not add any security, it’s just a different thing holding an alphanumeric value. They could just use RFID tags without the blockchain, the result would be the same.

    But my point is mostly that this is already an entirely solved problem, you don’t need very many bits to store a useful unique ID code, you certainly don’t need a blockchain-token-value amount of bits, and a printed paper tag is cheaper, easier to manufacture, and less environmentally impactful than a microchip.



  • Barcodes and QR codes do not have enough information for unique identification. (Well they could but they start getting bigger and bigger)

    This is not really true. A 16-digit decimal code gives you 10 quadrillion unique numbers. FedEx handled ~3 billion packages in 2024, so at that rate it would take them more than 3 million years to use up the ID space. You don’t need ridiculously long strings (e.g. blockchain tokens) for useful package ID codes.

    If you stored the 16 digits as ASCII characters (7 bits each) it would be all of 112 bits of data. The Micro QR format is more than enough to represent that data, with room to spare for error correction. If you used alphanumeric instead of decimal you’d have 62^16 unique IDs (UC + LC + 0-9), still only 16 ASCII characters (112 bits), and at that point you’re more worried about the sun burning out than you are about running out of package ID codes.

    But the real issue is needing these codes tracked and audited in a public manner. Instead of having a third party company trusted with all the cheese, you use a Blockchain with a public ledger. This doesn’t even require much processing power

    If you want the tracking to be useful, then every time a package passes through a handling station the ID needs to be scanned and the ledger updated indicating the transfer of the package ID from one station to the other. Then every node on the blockchain network needs to update their copy of the ledger with the new transaction data. Never mind mining, if you’re handling millions of packages per day then updating the ledger will create a stupid amount of network traffic and just eat processing power.

    since there’s no incentive to mine as many blocks as possible.

    Without mining, what incentive would there be for anyone besides the actual shipping company to host a blockchain node for this? How would it not still be “a third party company trusted with all the cheese”?

    Also, correcting any errors that get written into the ledger due to some handling failure will be extremely difficult if not impossible:

    Once a transaction is sent and confirmed, it cannot be reversed.

    I think the term “homeless” is really a euphemism that makes it easier for wealthy people to talk about poor people (if you have shelter, food, and are not living paycheck to paycheck you count as wealthy), and it results in misunderstandings about what the real problems are.

    Giving a house to someone who lives on the streets is a nice gesture but it doesn’t address the underlying problems - unemployment, unemployability, health problems, psychological problems, lack of social support structure, lack of supportive relationships (e.g. friends and family) - you can’t just fix someone’s life with a building.

    It’s like a grade-school-level understanding of the problem (“just give the homeless people homes! then they’re not homeless anymore! problem solved!”). Without putting in a real effort to support these individuals’ lives, to understand and address what put them in that situation in the first place, this is a temporary patch that will end in relapse.
