You can like or dislike generated images (if that's what they are—I haven't looked) but this post has nothing to do with scamming anyone, and given the wealth of technical information in the thread, including a video showing the product under development, it seems like a weird claim to arrive at.
Et tu, dang?
You don't see how this is misleading or fradulent (i.e. definition of a scam) in any way? A realistic image of someone wearing the glasses that don't exist yet, without disclosing it?
