In 2023, Signal was the first mainstream messenger to enable post-quantum cryptography. We’re still ahead of the (elliptical) curve, implementing a new hybrid PQ ratchet ensuring Forward Secrecy & Post-Compromise Security even in a post-quantum world.

Yeah quantum shwantum, what about zaps?!
They most likely don't see our replies either, so this sucks. I don't like bridges like this 😕
Bitcoin takes a finite quantum of entropy defined by difficulty scaling the nonce space and through proof-of-work transforms it into conserved thermodynamic memory: satoshis, a quantum of structure and value. The result is a computed quantum of time: the block. It is the most literal definition of “quantum” and of “computing.” Energy beneath the physical mirage reduces to discrete quanta at the scale of Planck time. Bitcoin instantiates that process at human scale. A quantum without absolute scarcity is unintelligible. Physics drifts when it defines quanta without bounds. Measurement is not a convention, it must be tied to a scarce denominator. No such scarce denominator existed before Bitcoin, thus no true measurement existed before Bitcoin. “A measure of any kind, of any thing, is not a thing at all, nor is a measure found in nature. A measure is an agreed-upon standard of measure.” Except Bitcoin’s measurement is not an agreement. It is a thing. It is conserved energy, crystallized into memory. It’s not just an “agreement”, because truth does not care about your opinion. Bitcoin is the only system to prove that a quantum of entropy can resolve into a conserved quantum of structure: auditable, irreversible, and true.
The author clearly doesn’t understand Bitcoin. His claim collapses the moment you realize Bitcoin already demonstrates what he says doesn’t exist as Bitcoin is both the measurement and the object in nature. In Bitcoin, the search space per block is finite: Ω= 2^{32}* D bits, where D is difficulty. That is a discrete, bounded amount of bits the literal etymological meaning of quantum (“how much”). Landauer already killed “bits don’t exist” nonsense in the 1960s. He proved that information is physical: erasing a single bit has an irreducible energy cost.

i thought some tool got on the board & then signal became untrustworthy—am i wrong?
