As someone who's been following this area for awhile, I concur. Meta has been around since 2012, but has no substantial technology that a clever consumer could buy and diy for themselves.

AR companies that are working on bleeding edge tech have started later and gotten a lot further than Meta:

- Microsoft Hololens - released in 2017. Incredible inside out tracking and mapping of stationary objects, decent resolution, limited FOV.

- Google Tango - released in 2014. First mobile device with a depth sensor and AR games.

- Avegant - founded in 2012. Developing commercial light field technology.

Meta's lawsuit seems like a desperate attempt to stay relevant without having a moat.
