This won't happen. I would even venture to say this can't happen. I don't mean that in the pejorative sense, but if this quote is true then it does demonstrate that Zuckerberg doesn't actually understand what made that "iPhone moment" the inflexion point it surely was.
Mark Zuckerberg isn't Steve Jobs. Again, not meant as a slur, but it's inescapable that Jobs was a master storyteller and regardless of what you thought of the man and the products, nobody could pitch like him. Zuckerberg certainly can't. Facts.
Lots of people who aren't Apple Enthusiasts perhaps don't comprehend how much pent-up desire there was for Apple to make a phone. People knew there was a revolution there to be had, if some company could just come up with the right sauce. And there was faith that Apple could be that company. Meta doesn't have the pedigree or the mythology. People don't care about what Meta makes in the same way people care about Apple. Coming off the back of the Apple resurgence fuelled by the original iMac and the iPod, there was an awareness in the wider public that Apple was capable of producing something truly kick-ass.
Most people still don't even know what the "metaverse" even means and I challenge anyone to demonstrate that Meta has even 10% of that same wider public awareness.
When you watch that iPhone launch, the cheer that goes up when he announces that Apple is making a phone, the visceral euphoria that fills the auditorium, is something that can't be faked.
To be clear, the Apple of today faces some of these same challenges in the inevitable launch of their AR/VR product, but the ingredients simply aren't there for Meta to have an "iPhone moment".
