Spatial computing as an idea is from early 2000s. It was in Wired and sci-fi pulp and something the graybeards would hobnob about. Sometimes it just takes 20 years for an idea to come to fruition.
I think he would love the internet access, think the web was stupid, and that Apple Vision is alien technology he dreamed of. He more or less spent his productive years defining the world we currently live in. I take him as man of vision and principal. He would be astounded by the tech and hate the content.
I was greatly disturbed by the product demonstration. After 72 hours I realized that since I work alone there are no real drawbacks to having a hands free computer. (I have been working in a 60'x30' studio that I have equipped with 8MP cameras, shopping for 4k and 8k projectors. The idea is to have the cameras act as an interface and use the projectors to create an image on the floor as feedback. The Vision Pro seems like it might be easier and cheaper. Although not as analog and collaborative.)
