>but mobile phones and computers haven’t evolved practically at all in the last 5 years.

Lets do a fact check on this, that time span is the iphone X to iphone 14 Pro. Taking one metric, the geekbench score has gone from 2156 to 5383. So in that time phones have become more twice as fast. It released with ios 11, I wont even bother to list all the major improvements between 11 and 16 because it's a huge list.

There is so much more to expand on this but when even the most obvious stats show dramatic improvement, there isn't any point detailing the differences in camera, connectivity, features, etc.
