Yes.

Meanwhile intelligence agencies says they want to stop encryption to help them investigate crime...

Lobbyists selected by rich people tell politicians who to appoint to lead agencies. These people give directives and can get agents fired for disobeying.

Stopping it means removing "single points of failures" like not having such a powerful hierarchy, in addition to accountability measures (independent inspections, etc)

Well, unless they also made key generation shitty, because that's equally plausible and would likely allow RSA keys to be broken (it's surprisingly hard to generate RSA keys safely)

Presidential pardons for state crimes don't exist. Claiming he's done it does nothing. Signing fancy formal papers saying so is null and void.

Unreliable certainly. For as long as there's radio coverage there's a way, but it used to be impractical to give passengers enough bandwidth. 20 years ago you'd have to ask the captain nicely to get a call routed (read: have an emergency)

If you allow civilian HAM radio, you go back a few more decades (not quite applicable to planes, but definitely applicable to boats). If you allow Morse code you go back yet a little further.

This one (bath thermometer) goes to 111°F

Irrational probabilities makes MWI impractical unless you interpret the branching much like a continous graph (as a visualization, see phase of matter graphs) with an ever increasing number of dimensions. And yes continous branching is weird

They're just contributing to perfect information, or, uh...

And why would a bunch of never-left-their-staters even care in the first place? They clearly don't want freedom of movement

This map won't be centered on the equator

EU have a freedom of expression law and multiple countries also have constitutional freedom of speech, including right to film police

Germany is also rather unique in having laws with opaque interpretations

Abstract

We show that a simple eavesdropper listening in on classical communication between potentially entangled quantum parties will eventually be able to impersonate any of the parties. Furthermore, the attack is efficient if one-way puzzles do not exist. As a direct consequence, one-way puzzles are implied by reusable authentication schemes over classical channels with quantum pre-shared secrets that are potentially evolving.

As an additional application, we show that any quantum money scheme that can be verified through only classical queries to any oracle cannot be information-theoretically secure. This significantly generalizes the prior work by Ananth, Hu, and Yuen (ASIACRYPT'23) where they showed the same but only for the specific case of random oracles. Therefore, verifying black-box constructions of quantum money inherently requires coherently evaluating the underlying cryptographic tools, which may be difficult for near-term quantum devices.
