What were you suggesting when you shared that gif and said you were pretty sure the demo was staged?
From what I've read, impressions have been good in general. There are issues that have been pointed out, that are worth discussing.
I'm suggesting that the stage demo was not authentic. That's it. There must have been reasons for that. It would make no logical sense to stage a demo if the product worked flawlessly.
For the rest of the posts, I'm simply not going to reply. I am, and always have been skeptic of this technology, and so far basic jumping, moving, and eye tracking doesn't convince me that it's here to stay, much less that I need to invest in it.
