The problem is that by doing that they’ve limited their device’s usefulness severely.
If some kind of killer AR app shows up on the Vision Pro, could it be put on the Quest? Let’s just assume it doesn’t need a level of processing power that the Quest can’t deliver. Would the software vendor just have to implement the entire interface from scratch or with Unity or something? Are there enough platform components on the Quest to be able to do the job?
I don’t know the answer. But I did see a number of developers mentioning online over the last year just how incredibly easy it was to get started with the Vision Pro compared to the quest. If you have a Mac you sign up for the Developer program for $99 and you get an IDE, compiler, simulator, performance monitoring, full UI library plus documentation. It’s early days for some of that stuff, but all the batteries are included. From what they said it was far far easier to get to “hello world” than on Meta’s platform.
