  • Consciousness is not part of the observer effect (which is itself named in the most infuriating way possible, specifically because it makes people think that the universe is somehow aware of when something sentient is looking at it). “Observing” a particle requires interacting with it in such a way that you meaningfully affect its current state of being, whether that be deflecting it in a different direction than it was going or changing its velocity, and therefore it is impossible at a quantum level to be a passive observer that does not influence the outcome.

    In the case of the double slit experiment, if unobserved light will act as a wave with interference and if observed then it acts like a particle. The reason for this is both complicated and simple: light behaves as a wave due to probability. There’s no way of observing a photon without influencing it, so therefore the best we can do is say it has a certain probability of being in this collection of spaces, which in the case of photons is a wave (because it can travel in any of a number of directions outwards from the photon emitter in the experiment, but all going away from the emitter and towards the wall the slits are cut into). For the purposes of this probability wave, the start position is the emitter and the end position is the wall behind the slits, so averaging out a large number of photons will recreate the interference pattern on the wall.

    However, if you observe the photons at the slits to try and figure out which slits they’re going through you have influenced the photons and thus collapsed that probability wave into a particle, and in the process created a new probability wave from that moment onwards which has the same end position as the original wave, but now starts at the individual slit. From its perspective, there is no second slit, so now the wave acts as if it is in the single slit setup because from its perspective it is, hence the loss of interference.

    Nothing here has anything to do with consciousness. You can recreate this experiment with no one in the room and it will behave exactly the same, and has a sound (if very confusing conventionally) mathematical cause.

    On a side note, string theory is effectively unfalsifiable and therefore completely useless as a scientific theory.








  • and packaging this into a system that meets the scale and reliability requirements to make it commercially viable hasn’t been reproduced to date

    Your overall point about EUV being difficult isn’t wrong, but this line is really where the typical liberal forecasting of China’s capabilities fall apart: they don’t give a shit about it being commercially viable, they give a shit about having the industrial capacity.

    The reason why EUV is more or less a cartel monopoly in the West is that it’s a cobbled together collection of scientific principles that work well enough that the first few companies that figured it out could make insane profits off of it, and then proceeded to patent the shit out of it to prevent anyone else from doing so. The engineering behind EUV is… not great from a reliability standpoint, most notably the fact that EUV has an average downtime of something like 10% (meaning your fabs are offline 10% of the year for maintenance), in large part because you’re shooting little droplets of liquid metals with a high intensity laser which tends to splatter and require cleanup. There are potential alternatives to this process for creating the kind of UV light you need for lithography, such as particle accelerators, that are theoretically superior but the R&D into those alternatives costs tens of billions of dollars with no guarantees that any of it will ever become profitable, so Western capital doesn’t bother trying.

    China doesn’t have that profit restriction. It needs the ability to produce bleeding edge chips to remove its reliance on an increasingly hostile West, and it has not only the engineering and scientific power to brute force that kind of R&D but the ability to devote a sizeable portion of its national resources to doing so. It doesn’t matter if its profitable, it matters if they’re able to decouple a critical industry from the West and ignore sanctions accordingly, and that has infinitely more value than a shareholder dividend, so they will put the resources into doing so and, inevitably, they will figure it out. And from what we’ve seen over the past 2 years since the trade wars have started, they’re not only succeeding but doing so ahead of expectations, in large part because increasing tensions have made life a living hell for Chinese scientists and engineers abroad working in these industries due to racism and suspicions of spying which push them to emigrate back to China and lend their expertise there instead.

    In 20 years, chips made in mainland China will be competitive or even superior to their Western counterparts unless the West undoes 50 years of neoliberal rot overnight and replicates what the CPC is doing for silicon manufacturing or the CPC collapses and China experiences the same shock doctrine that the former Soviet states did in the 90s, and neither of those outcomes look likely right now.
