Well, let me assist. The 13 is way better than the 12, which is way better than the 11. The camera on the 13 is hands down the best camera yet on any mobile device and was sufficiently better that I and millions of others dropped a cool grand to get it. And guess what? If the 14 is better enough, I'll get that too, and be delighted about it!
I get that many phones are now "good enough" for the more basic use cases but that doesn't mean strides aren't being made in other dimensions. You might not care, but others sure do.
