This is just people trying to talk down the stock.
The 14 was no more innovative than the 13 which was no more innovative than the 12 which was no more innovative than the 11 which is the last major innovative phone that Apple’s released.
There are definite hardware updates to the 15 (wifi 6e and USB-C among them) but this is obviously an interim release for a major update next year to coincide with their Apple Vision Pro.
I’m still using my 11Pro, it works just fine. I don’t know how much more technology they can pack into these things.
