Literally every product Apple has ever released, with the POSSIBLE exception of the iPhone, was not needed when Apple released the first version. People didn't need a personal computer in 1984, people definitely didn't need a portable music player in 2001, a tablet in 2010, or a smart watch in 2015. But I think you'd agree the Mac, iPod, iPad, and Apple Watch are successful. And while I'd argue a cell phone was close to being needed in 2007, plenty of people didn't have them. That doesn't mean the Apple Vision will be successful, but saying it never will be because people don't NEED it when it's first released is really, really short-sighted and silly.
Maybe it's because my career has been as a project manager and now in strategic planning, but the inability of so many on here to look a few years into the future and think strategically is mind boggling. For example, if Apple is working with major sports leagues to develop live immersive front-row seats (which is heavily rumored), in a few years a lot of sports fans are going to think they NEED something to watch that content on. And guess what, because Apple released AVP this year, the "Apple Vision Air" that comes out just in time for that new service in 2027 or whenever becomes a hell of a lot better value proposition because it's a few years down the line, Apple can make them at scale, they're cheaper, lighter, there are more mature apps, Apple and developers have figured out what works and doesn't, etc. If they waited to release something until then, 1) the NBA or whoever doesn't build out that infrastructure for an unreleased product and 2) this awkward phase where there isn't ton to do, not a lot of content to watch, etc. happens when millions of them are out in the wild vs. a couple hundred thousand early adopters who can afford to spend $3500+ on a new product category that isn't needed. And imagine the "APPLE IS FAILED/DOOMED ARG" headlines then.
To be clear, no promises that is going to happen. Maybe the bandwidth requirements of live immersive sports makes it DOA for ten years and at that point Apple Vision has been killed off. Or maybe it's so expensive that the MBAs working for the sports leagues determine that they couldn't charge enough to make it worth their while. Or maybe you naysayers are right and 95% of people will never wear goggles until all this technology fits in a normal pair of glasses with all-day battery life in like 50 years no matter how amazing the content is. But if Apple doesn't get started now skating to where they think the puck is going to be, then the future they are pushing towards definitely doesn't happen.
