What will become "the next iPhone"? Have we reached the height of evolution?

So I've just been thinking about the fact that modern phones have been frozen in time. I recently saw a post on the r/Zillennial subbreddit showing off a phone from 2014, and it got me thinking....they haven't really evolved that much. 

I remember when it felt like tech was shifting rapidly, growing up and going from using VHS/DVDs as a late 90s baby, then being excited to own an mp3 player, then an iPod. Each evolution felt so fun, like I could truly feel time passing by and changing rapidly. Then....came my iphone. I got my first one in 2011, and it was revolutionary. I instantly downloaded a bunch of books to read on the go, and loved browsing music streaming platforms like Pandora. It truly felt life changing, going from having to carry so many things separately (my mp3 player, library books, cell phone) and having it all condensed into one device. 

Today it's just begun to feel that was the height of technological evolution we'll see for a while, when it comes to modern devices. When looking at the video, it occured to me that nothing's dramatically changed over the last 11 years in terms of cell phones. Sure, the cameras have gotten better, the storage is better and the connection. Outside of this, most of the "evolutions" that happened have occured within the phone's interface. Like app or software updates. 

Seeing the video from 2014, had me realizing that no other recent decades have felt so...stunted. Like if you look at phones and music devices/audio formats over the past century, you can see a CLEAR evolution. From the 1980s to the 2000s, you can watch phones evolve from rotary phones to cordless phones, see music go from 8tracks to tapes to cds, and mp3s.

But from 2007 to 2025... almost 20 years later (the exact time difference from 1982 to 2000), we've been holding onto one flat faced rectangle with a touch screen. Is this truly the farthest it can go? I get that we've consolidated so much into the phone - calculators, internet, GPS systems, cameras, etc... it feels like there's nothing exciting around to corner to reach to next. People often joke online about the iphone upgrades being damn near the same plus a better camera, and it was a hyperbolic reaction back in 2012, but AN ACTUAL REALITY TODAY.
