I disagree. I find it fascinating to see what the current difference is between a phone camera and a state-of-the-art system.
It narrows with each generation, which both benefits all of us and spurs Arri (and others) to invest further in R&D.
But what's amazing is that in a relatively short period of time the iPhone has gone from the quality of the original version to something that - with a bit of Neat video in post - can work in a pinch, so long as you don't mind losing some control over depth of field.
Once computational photography gets even better at that (and Apple's Portrait mode is already impressive) you wonder how the high-end models will justify their price difference in another decade's time.
