It should be said that PDF signatures are a very fragile design, leading to a pletora of security issues: https://pdf-insecurity.org/ A core problem is that a pdf signature does not necessarily cover a complete file, but ca

I mean you won't find the ultimate answer, but I found the writings of Oliver Burkeman on these kinds of topics interesting. He's a bit of an anti-productivity guru (aka recognizing that these are important issues, but being highl

That would still be a terrible idea. If you do it domain-based it's obviously insecure (validate -> change a-record -> attack), if you do it IP based you basically allow attacks on cloud services that rent cheap virtual servers.

If you get a high paying job you are very likely not looking rationally at the harm done by your job. My understanding of ETG is that people have the goal to earn as much money as possible so they can donate more. But if you take the idea o

Sure, I just don't think error-free qubits are a thing (or will be in the future). I don't think anyone seriously expects quantum computing to work without error correction.
