I didn’t say what I think matters more than what you think. I said what you think doesn’t matter relative to the immovable limits of physics.
I’m all for hoping new and interesting innovation in the world of computing tech is possible. But it’s really tough to do that and have reasonable discussions about it if some people like you on this forum just don’t understand - or aren’t willing to accept what you might not know - about fundamental aspects of what’s within bounds to dream about and what’s not.
It would be like insisting the AVP could eventually facilitate time travel, “just give Apple 5-10 years!” So, no disrespect here: my comment was trying to point out that one of the things you want literally cannot happen.
OK, so let's have a conversation.
Two sticking points for me,
First what are the "immovable limits of physics" that you suggest which would prevent lightweight glasses from being developed? I surmise that I disagree with your assumptions here, but let's hear them.
Second, by saying "people like you" you seem to assume I am quite ignorant about the situation required, and the implied connotation is rather condescending.
Also, what do you do for a living, what is your education, that back up these claims? What is your expertise and/or sources of expertise? I'm happy to learn from someone who truly is an expert in this area. (this is what I meant about whose opinion matters more etc.)
Let me share a bit about myself, before you continue to assume things about me.
As it turns out, I have a computer engineering degree, work as a software engineer, and know people on the Vision Pro team. As a hobby I follow silicon and hardware design and optimizations since I find it interesting and reminds me what I studied originally at university. Now I haven't worked on the headset teams directly, so certainly there are things I don't know, but I feel that I have a high level grasp on whats required.
I am not making 5-10 year predictions blindly or with wishful thinking analogous to time travel as you suggest.
I am thinking about the progress of silicon. If Vision Pro is a baseline, Apple needs M2 level of performance in the size and power constraints of an Apple Watch to make a compelling glasses style device. If they can get to AirPods form factor, even better.
Let's look at history, Apple has basically got M1 performance into iPhone form factor with A17 in 3 years. Furthermore, in certain ways it actually outperforms an M2, (newer GPU etc.) so perhaps A17 is all Apple needs for glasses. Furthermore, with the S9 chip they have A15 architecture from iPhone 13 Pro in the watch, this was done in two years. Now, its just the E cores, so performance is maybe closer to A12 or A13 (iPhone XS, or iPhone 11), so in about 5 years they have iPhone level performance in a Watch.
And this continues forward as well, as TMSC (and everyone else) has no indication of slowing down shrinking process nodes as well as upcoming material changes performance keeps drastically improving; essentially, Moore's Law is not dead. If you don't believe me, there's a good talk from Jim Keller (world renowned CPU architect) explaining this in more detail.
Therefore, it seems reasonable that Apple can achieve M2 (or at least A17) level performance in a Watch size thermal and power constrained device in 5 years time. And perhaps in even smaller sizes by 10 years. This is primarily how I came to my prediction.
In addition to that, with glasses you need transparent OLED screens or a kind of micro projector, both of these exist, and continue to improve. I'm not totally sure on the time frame of these technologies however, so if you have insights there I'm open to hearing them.
Also, while you do still need cameras and lidar to track objects, you don't need constant video passthrough for the user and so no need for the R1 chip, so that should help thermal and power issues as well. It may also be the case that portable glasses one wears outside may not have all the features a larger headset has, (same as iPhone vs Mac) but this does not prevent the device from existing or being compelling.
So, what about this "literally cannot happen" ?
