You’re confusing skepticism, particularly in a business context, with denial. I’m not saying new technology shouldn’t exist — I’m saying that every generation of hardware is constrained by physics and engineering trade-offs. Foldables today, and inevitably Apple’s future version, are compromised by design: a hinge, a flexible plastic display, a thermal envelope that’s smaller per watt than either a dedicated phone or tablet, battery size constraints, etc. Those are measurable, not opinions.
When I say a foldable iPhone would be worse as both a phone and a tablet, that’s not rhetoric: it’s reality. It would be thicker, heavier and less durable than what is possible with the current technology, and when unfolded, 10–13 % less screen area than even the smallest iPad. That’s a regression, unless the user explicitly values things about it to offset these trade offs.
As for Vision Pro... even Apple underestimated how niche it would remain at that price. The Glasses may come later, but they’ll need to cut that complexity dramatically just to make sense commercially in a niche sense, let alone for a wide market. The Glasses have a lot of their own problems (e.g., they will let in reams of light since they're not sealed, and that can and does wash out the displays).
Innovation isn’t about churning out gimmicks; it’s about solving real problems in a better way. There’s a difference between advancement and compromise disguised as advancement...
