  • To properly answer, we need to define what we mean as “airborne” which has gotten a bunch of people very upset recently. Prior to the COVID pandemic, the transmission model for respiratory viruses focussed on 3 distinct models of transmission:

    • Fomites are collections of excretions on surfaces containing live virus. An infectious person cough into their hand, pick their nose, or similar, then touch the doorknob. The next person touches the doorknob, then their mucus membrane (nose, eye, mouth) and they get infected.
    • Droplets are large collections of excretions that are transmitted during talking, shouting, singing, coughing, or sneezing. They are ballistically expelled, but don’t remain in the air. An infected person expels these droplets, and must be in range of another person who is struck by these droplets in their mucus membranes to be infected.
    • Finally, airborne transmission occurs when micro droplets small enough to ride on air currents are expelled from infected people, and non infected people inhale them into their airways.

    COVID was presumed to only be transmitted through the first 2 methods. But weird things were observed, where transmission occurred when people (or ferret model experiments) were separated by barriers through which ballistic droplets couldn’t pass, like air ducts with multiple 90° bends. People also got sick after being in rooms many minutes after infected people had been present, long after ballistic droplets would have harmlessly fallen to the ground.

    In reality, droplet models were just close range transmission, and airborne long range transmission of bio-aerosols, or micro droplets created from breathing, shouting, singing, coughing, or sneezing. The range was more a function of the transmissibility of the virus. Highly infective things can infect at low doses at long range. Less infective things occur with much higher doses, when people are quite close to one another. This folded in the prior models quite nicely. It was, however, not well accepted.

    If a disease is to be transmitted by bio-aerosols, the disease vector needs to be able to enter the body through the surfaces with which it will interact upon being “breathed in”. This doesn’t work well for the STI viruses or bacteria, nor the malarial parasite, as they aren’t actively expelled in the respiratory system, so don’t generate bio-aerosols, and require access to highly specific host cells not easily accessed through the respiratory system at the necessary volumes to create an infection.

    So, no, not really possible for non-respiratory viruses to become “airborne” in that sense.there would need to be a LOT of intermediate steps.

    But diseases that we used to consider to be transmitted by the now defunct ballistic droplet model can become “airborne” (instead of “droplet”) if their ability to infect a subject becomes more successful at lower doses of pathogen such that it can occur at longer range, and over longer times.









  • You can absolutely set up an AppleTV with no other Apple device in your possession. It is a very good player for many things but much of this is dependent on your choice of application. For compatibility and no transcoding, Infuse is the best I’ve found, provided it’s pointed at a Jellyfin instance. Not a great choice just pointed at a local or cloud SMB share (though possible) as its cache gets cleared frequently.

    AFAIK, Shield Pro remains the only option that can play back Atmos from ripped media, but would be happy to be corrected on this.




  • There are multiple versions. I suggest you get these from the official site (free, but donations support the cost of equipment, purchasing film reels, and HDD space) and make sure you have the most recent 4K version. I don’t think you will know with certainty which version you have if you try to get this through other means.

    I get the sense it was a tricky restoration due to the film stock (and film scanning equipment) they had available, which was spread across 16mm, Kodak 35mm, and Fuji 35mm (which had better colour preservation but was incomplete). They explain it much better on their website, but it is an iterative process, and earlier versions might have a different quality.







  • Infuse for Apple TV will do this. You can point it to any folder on your NAS as an SMB share. It’s how I play back my own Blu-ray Discs, 4K or otherwise. It doesn’t do menus that I remember, but you can select the title easily enough.

    Highly recommend also pointing it to your Jellyfin instance and using that as your front end for other files as it seems to me to have the best ability to do direct playback without transcoding, and the fewest hiccups for audio playback sync issues which can be annoying.

    While you can just point Infuse directly at your other folders, its metadata cache gets dumped frequently by the OS, and it has to get rebuilt which is slow and annoying when you just want to watch something. Pointing at Jellyfin also lets you use whatever custom Jellyfin posters you’ve selected which helps for keeping special versions/collections identifiable visually.


  • To give a non-snarky answer, it does AR with external cameras and an incredibly low lag such that those who have tried it have said makes it almost natural (the resolution apparently isn’t perfect, but there is no discernible input lag when looking around which happens on other similar devices). But you can dial up the opacity to wind up in a fully VR environment. So, it is in fact, both.

    Your question about software is a big one. Apple is advertising 1M apps available at launch (good) but these are iPad apps, which can run on Vision OS without any modifications by the developers (not so good). That does not mean it will be a good experience. I was listening to a podcast today where a developer clearly stated that after getting a chance to try their app on device at a lab, they totally stopped development because they missed the mark completely with their imagination and the simulator on how it should work. You’ll still be able to run their iPad app, but until they get their hands on their own hardware to iterate more rapidly, they’re giving up.

    All that to say it’s unclear how many apps will be natively designed to work with it on launch, and if these will be any good.

    Thankfully I don’t live in the US so I am immune to this particular reality distortion field. For now…
