  • Well your first statement is a subtle strawman. Ross said this way is the only way, because no one else is trying, not that it was the right way.

    Secondly, fallacy fallacy, just because it’s a false dichotomy doesn’t mean it’s not also correct. Can anyone just start up another initiative now? Not technically, but practically. Or would any serious attempt just join this movement to add to the momentum. Then if this fails, when can another attempt be made, how long till the ‘political will’ burnt by this campaign is regenerated?




  • No, I am not sure that I am.

    Photonic processing, whilst very cool and super exciting, is not a quantum thing… Maxwells equations are exceedingly classical.

    As for the rest it’s transistor design optimisation, enabled predominantly by materials science and ASMLs EUV tech I guess:), but still exploits the same underlying ‘quantum 1.0’ physics.

    Spintronics (which could be what you mean by 2D) is for sure in-between (1.5?), leveraging spin for low energy compute.

    Quantum 2.0 is systems exploiting entanglement and superposition - i.e. qubits in a QPU (and a few quantum sensing applications).



  • Good question. It would be application specific. I think evanescencnt wave coupling in EM radiation is considered " very classical" (whatever that actually means). But utilizing wave particle duality for tunneling devices is past quantum 1.0 (1.5 maybe?). However, superconductivity tunneling in Josephson junctions in a SQUID is closer to quantum 1.0, but 2.0 if used to generate entangled states for superconducting qbits for quantum computing.

    Clear as mud right?



  • Quantum Physics Postdoc here. Although technically correct this is also somewhat misleading. You need the band structure of solids, which is due to quantization and Pauli exclusion principle. The same quantum mechanics that explains why we did those strange electron energy levels for atoms in highschool. The majority of quantum mechanics, however, is not required: coherence, spin, entanglement, superposition. In the field we describe semiconductors as quantum 1.0, and devices that use entanglement and superposition (i.e. a quantum computer) as quantum 2.0, and smear everything else in-between.

  • Ok, so I don’t think I explained my thoughts on crushing well. It’s not, in the real world, bludgeoning damage. I can see why they chose to not have a crushing damage type and just use bludgeoning though, as anything susceptible to one would be susceptible to the other.

    Ugh, bringing AC into it is a mess. But I think your approach results in the tennis ball lasting an average of 20 hits in a game between two strong opponents. And less time the better they are at playing tennis?

    I think you’ve moved the goal post, but perhaps in an interesting direction. If the goal is to simplfy the damage types, what do you lose by replacing force attacks with other types? I think you lose an impact type of damage like damage to creatures you can’t hit with a hammer. Magic missle goes from best to worst spell.



  • High pressure fluid injuries are significantly different, but we’re moving off track.

    Let’s come from the other direction. Bludgeoning, slashing and piercing all do damage through the application of force. However, the damage they do is amplified and relise on a particular susceptibility of the victim.

    Bludgeoning amplifies is force through rapid impact time.

    Piercing amplifies is force through a sharp hard single point.

    Slashing is more complex, but it amplifies with a sharp hard edge kinda.

    But these ‘tricks’ to deal more damage don’t work on everything. For example bludgeoning requires ‘inelastic deformation’ before movement. I.e. a bat breaks a skull but not a tennis ball. I can see why crushing is put in this category, it recognises that damage is due to the susceptibility of the target to be inelastically deformed (bruised, broken bones, crushed organs w/e). Everything has an inelastic deformation point, put a tennis ball in a press and you can crush it. But in this case it’s not that the ball is susceptible to bludgeoning damage, it’s just that you have applied lots of force.

    Same with piercing, the effectiveness of a spear is reduced by something that can distribute its force over a larger area. Which doesn’t matter if the ‘spear’ has a huge amount of force behind it. At which point it doesn’t matter if it was a spear with a sharp point or just a rod (or jet of fluid).
