I'm going to say the following 'Tongue in Cheek' as a reply to the few who wish to argue that Tim was fine on saying that, despite it not being able to do what a Mac and iPhone can do.
And your argument is that, it COULD be programmed to do those things, hence what Tim said was perfectly valid.
So, let's take your viewpoint, and I'll put forward the following imaginary scenario and see if you stick my your view
---Made up news to prove a point---
When interviewed about the new Quest 4, Mark stated the following:
"It can do anything your Mac or iPhone can do and more"
I'll now use your argument in defence of Mark here, and say that Mark was really just saying that it has the potential to do all of those things, once the developers and meta have developed the software to make this a reality.
We know the Quest 4 can't do what an iPhone or Mac can do today, BUT it has the potential to be programmed to in the future.
