I don't agree, I have an iPad Mini4 from 2015, and that's still good for most day to day tasks (although it feels slower than in the beginning thanks to iOS updates being less optimized).
Same with my mid-2014 13" MBP. While my M1 MBP is a lot faster for things like building complex C++ code bases, for stuff like web browsing the old Intel Mac doesn't feel much different.
Compared to the incredible hardware progress between 1995 and 2005 (where a 2x increase per year was quite normal) it definitely feels like we're on a plateau since around 2010.
