People seem to really be struggling with the idea that Apple could have invested heavily into something that's quite simply ... "a mistake"
On the other hand, there are also people who seem to believe that Apple has lost its spark and every new endeavour is doomed to fail. We saw it with the Apple Watch, the AirPods, apple silicon, TV+ etc.
I suppose if Apple releases 10 new products, and you keep arguing that every single one will fail, you may eventually get at least one correct (and 9 wrong). On the flip side, if I argue for Apple, and even if one does fail, it's still a tally of 9 correct and 1 wrong, yet the critic who got that 1 "prediction" right is somehow being given more weight than me having 9 right.
All because it no longer seems categorically cool to root for Apple these days. And even if, in the process of trying to get that 1 doom prediction right, the critics have gotten enough wrong that in the greater scope of things, they would still have been wrong, in that they don't understand business in general, and they don't understand Apple, and their words really have no more weight than some random stranger on the street claiming he knows what the next winning lottery numbers are.
In what respect? Hand gestures? Eye tracking? Those are different ways to interact with software, but are they actually better? More intuitive? What is the inherent flaw with current computer interfaces that this solves? What productive task can you accomplish with Vision that simply isn’t possible with a traditional interface?
All of these questions and more have to be answered before such a system could even begin to compete with current software/hardware interfaces, let alone replace them.
To use an analogy, when I bought my first ipad, I was comfortable bringing it on my overseas school trip with my students in lieu of my laptop, and it was better at its assigned task of blogging about our daily experiences, and handling the daily admin tasks.
The iPad wasn't any more powerful or "capable" than a laptop, but it excelled in terms of its longer battery life, ease of use (apps like Wordpress made it easier to upload blog content over a traditional web interface, plus I could take photos directly with its inbuilt camera) and cellular support meant I didn't have to tether from my phone. The form factor also made it more convenient to work in cramped spaces like on the bus, or while walking around. This allowed me to complete my tasks by the time I returned to our hotel, freeing up my evenings.
All these came together to make the iPad situationally more versatile than a conventional laptop under the right circumstances. That's what these alternative computing platforms offer - options where traditional solutions would otherwise fail users.
The question very often isn't what can be accomplished with the Vision Pro, but how it rethinks the way some tasks are carried out. When I am outdoors, I can't realistically bring a 32" monitor along with me, but I can bring along my vision pro which then doubles as a larger screen when I am at Starbucks. Passthrough gives me awareness of my surroundings, and customers don't get to see what's on my screen (so better privacy).
When I can control my interface with my eyes and hands, I don't need a keyboard and mouse, thus freeing up my hands. A headset means I don't have to hold up my phone with my hands in order to consume content. And when you are able to use the Vision Pro in scenarios where a laptop or PC simply isn't feasible, that's when new use cases arise (and sometimes even end up replacing the old ways of doing stuff).
People seriously need to look beyond traditional PC tasks like spreadsheets or video editing as the be-all and end-all of "productivity", as though no other scenarios exist.
