  • That’s not how physics works. If you are really interested in such issues read a book on foundations of physics or history of physics to see how physicists arrived at the most famous equations (Einstein,Dirac, Schroedinger or Newton), they are basically “bets” guided by physical and mathematical assumptions, but that is far from being “proved” or “derived”, there are no rigorous proofs or derivations involved. The uncertainty remains until an experiment or observation confirms it or rejects it. There’s no such a thing as “proving” a physical theory, for the simple reason that any physical theory works in a limited regime or range of validity. Newtonian gravitation and General Relativity are both valid and succesfull theories within their range of validity, but they contradict each other mathematically, in one theory gravity is a scalar field and in the other is a tensor field, so you could use the mathematics of one theory to refute the other, so it makes no sense the concept of proving a physical theory mathematically. You only try to axiomize a theory once is well established, but it’s irrelevant concerning its validity.

    You know that what you said is pure speculation based on personal experience, random publications, ideology or mainstream and social media, which is the only way you can reach that conclusion, unless you have peer-review publications with the statistics of worldwide usage. If you lived in Africa you would say that Bitcoin is godsend, as you can hear it from many africans


  • Faulty generalization That some scammers or greedy people in rich countries are promoting it like a ponzi scheme to benefit themselves doesn’t mean every person use it in the same way. Some people use it for its savings in a highly devaluating currency (my use case), others for money laundering, or to send money to Palestine, or to flee a collapsing country because of war and avoiding their money being seized by the policy at the borders, for ransomware, or creating circular economies in poor countries, to donate to human rights activists in dictatorships, to buy drugs, etc, etc these are just some of the dozens of verified uses cases. That’s what happens when a technology is free and permissionless, it’s not good or bad by itself, it’s as good or as bad as the person that uses it. AI is being used to scam people and to detect cancer more precisely than the best experts. That’s and inherent feature of free software. Lemmy is a perfect example, would you promote not using it because there is an instance used for child porn?

    The carrier can track a phone without sim card but it’s not the case if you turn on airplane mode. The whole point of airplane mode is to prevent the phone from emitting any signal to avoid interference with critical aircraft instruments. I don’t see any company risking to circumvent such a critical security feature, it would be easily verifiable.
