The big difference I see comparing computers from 1986 to today is that our demands for computers today are vastly different. The way we use computers today might have some similarities to 1986 for some, but for the average person its massively different.
However, comparing a computer from 2016 to today, its not nearly as far. A desktop at home I use pretty consistently is running a Core i5 from _2012_ and otherwise works fine. Other than VR gaming there's rarely a task I have that the old computer can't otherwise do, other than run Windows 11 I guess. Everything I do today on a phone, I did the same on a phone in 2016. Messaging, phone calls, email, calendars, apps that are largely interacting with web services to render images and text on a screen, streaming video, etc. All things I do today, all things I did in 2016.
Honestly my phone use cases haven't evolved much since 2010, maybe even several years before then. Things maybe look a little fancier, the cameras are for sure fancier, but the fundamental use of the device _for me_ hasn't changed.
