  • You could say the same for a finite element model. A junior engineer with just 4 years of training can solve, explicitly, the deflection at the center of a slender, simple-simple beam of prismatic section and produce an exact (if slightly incorrect) answer. Building a FEM of the same can solve the problem and take longer (to make the model) with similar accuracy, both of which are good enough for design work.

    Only a fool wouldn’t have a FEM around though, as it can solve problem that would take centuries for a human to solve. They may as well make a cartoon with the child digging a 3” hole in beach sand and then showing a backhoe making a jagged edged hole of the same size.

    I have own a rift and Q1, 2, and 3 (plus some older, but polished, Cardboard products) but have NOT had a VP demo. The jump from fresnel to pancake lenses - for productivity purposes - is substantial and I expect the VP’s moderately higher resolution to be enough to make the headset actually productive (Q3 is close but still resolution handicapped). I expect the tight integration with OSX to be useful and, if I were (a) on OSX (b) didn’t already work on an 8K monitor and © was a digital nomad or had no dedicated office/room in which to work, I could see a use case for them. Having attempted to work in i(Pad)OS professionally as a remote platform, the standalone capabilities might be useful for a blogger or journalist but is utterly unsuitable for professional work, even less so without a dedicated keyboard and mouse/advanced multitouch track pad. Again, I’ve not used the VP hand-sensing for advance selection* but my expectation is that it is still in its infancy, even with (and perhaos hindered by) eye focus selection.

    My hope is that $3500/pop will allow more research, more fine tuning, and advancing to vision limited resolution (Apple is still a factor of 4 short in pixel count, and a factor of 6+ short of my desktop monitor) for future headsets.

    * multi-functional, 3D manipulation of, say, finite element model components or full building/industrial models in a program like Revit or multi-assembly models in Blender or Fusion360, where you have 4+ key modifiers plus 3 buttons and two scroll wheels for fine manipulation and hundreds of quick-key commands)










  • Oh, it definitely does. A copy does not need to be verbatim - derivative works, of which even an inaccurately memorized copy would certainly apply - to be infringing. Otherwise a re-encoded copy of a video - having been entirely changed through the encoding process - would be a new work. When I sing a song from memory, it’s effectively reproducing the equivalent recorded copy from my brain. Of course, the performance is yet a new copy - and I can be sued if I were to change the lyrics or notes outside of the specific contract under which I perform (performance) or record (mechanical). Broadway show owners do this all the time (prohibit changes of words and characters, among other alterations) - and generally they win in court if challenged, shutting down shows and cancelling performance rights


  • Would not the act of memorization an infringing copy? Copyright itself does not allow a provision where a non-ephemeral copy may be stored, regardless of the medium or duration. You would, of course, have the positive defense of fair use - if you were sued for your infringing copy, you could mount a defense that the storage falls under the fair use provisions, but you would still be required to defend yourself at your own expense. Would it make a difference if we, one day, developed a method of reading memories. Someone with a photographic memory could then be used to recreate the work from their copy - clearly a violation, and hence the storage is a violation (excepting backup/fairuse - which is still an infringement, but a special case of permitted infringement)
