Thanks for the reply, even though I was hoping it wasn't basically hearsay and speculation (which it unfortunately is). Abovitz has repeatedly said that they absolutely want their tech to be safe enough for kids to use, so perhaps the safety concerns are not based on facts? Magic Leap apparently has active occlusion, and can run the spectrum from VR to AR/MR; pretty sure that makes it the potential leader, not an also-ran. I guess we'll see soon enough. Exciting times.
