I wonder what the acceptable collisions/delivery needs to be for it to match last mile truck safety level (ie UPS trucks are big and run into things with non-zero frequency)

Throwing up hands and saying: internalizing the externalized cost is "ridiculously expensive" is not proof it doesn't work.

The examples of the a la carte exercise brands referenced (SoulCycle, etc) are quite ineffective arguments -- those are successful businesses with loyal, high retention users because they provide specific, high value products to the users.

Short-term thinking is how hegemonies end.

Burner email services like AnonAddy, iCloud "Hide my email", et al work well for actual receipt but also provide isolation.

On this topic (parallel postulate), it took ~2000 years from Euclid and then 3 people all came to the same conclusion independently within ~10-20 years.

Progress is weird.

The specific controversy was whether without the parallel/5th postulate, there existed a logical contradiction, i.e. proving the parallel postulate

Yet, OP is repeating the same logical fallacy: the absence of a result is not a result of absence.

Making a hard, arbitrary deadline is a pretty extreme thing to do. ie Higgs Boson was a lot longer between theory and experiment than this.

Non-Euclidean geometry (geometric axioms in which one postulate is rejected such that the 3 angles of a triangle are not exactly 180 degrees) was considered a meaningless word game and fundamental mistruth.

Later, non-Euclidean geometry was actually essential to modern physics.

It's intellectually sketchy to judge future value by the present.

The legit criticism with a legit recommended change is even better.

A time and technological gap always exists between theory and a plan for experimental confirmation. Some gaps are fairly short. String theory's gap is undoubtedly long, not for lack of resources.

This gap justifies tapering the allocation of attention and research resources (funding, students, etc), which got lopsided following the strong marketing campaign driven by Greene.

What's your estimate for hardware costs? You can't get phone+service for $20/month. What if they have limited or poor credit?

Probably, but it wouldn't be the first time an axe grinding broke a sponsored monopoly.

It's ~$1/person direct, but how much indirect cost? Things become inexpensive when automation and technological progress makes them so, and the code copyright and restriction is a major barrier to do that.

The bigger issue is software development, imo. eg the IT team at a hospital or the medical office can't build a tool to help coding efficiency or accuracy. Further, public resources/websites with code-related information get DMCA takedowns. It's a stranglehold on innovation/progress.
