If Q hadn't mentioned Project Looking Glass I would agree. Personally I think it's likely   5f3  that Q didn't intend to reference time travel, but instead the old open source project that was going to bring 3D to operating systems. Why did PLG go dormant? Was it related to Steve Job's death? I remember thinking it would be the next big thing, but it never got anywhere. Instead we have intrusive spyware infested operating systems, Win10, Apple turning off functionality of older devices to sell new ones, and Linux, with it's overly text based operating system. I wonder how far the spooks have taken PLG. Eric Schmidt was involved with this as well, Google plundered Sun, Apple, YT etc, then he took a Defense job? And of course to support the DS and Obama.
