There isn't much progress in phones.

There was a period between 07 and 2016 (maybe) where each new generations of phone was a big leap in quality and capabilities, so I admit being in tech, so well paid and actually professionally concerned by the evolution I was on a 1 to 2 year cycle for a while. That reminded me of the evolution of computers in the 80s/90s...

Now, I recently I broke my galaxy S8 from 2017 and went to check new phones and of course looked at the current flagships and ... meh... Yeah they are better I mean it's 6 generations later but they are not that much better. My old phone could already do 90% of what they do and 100% of what I need and it's just not worth it, especially since I'm pretty sure my income hasn't followed the same curve as flagship phones prices.

So yes, nowadays even a 7 year old phone is more than enough for the vast majority of the population except for people who need a status symbol or some weird use at the margin I can't think of. (An no, your photo sucks donkey balls and no one cares about them and you don't need 12 sensors and an AI coprocessor for your tiktok stories that only 3 peoples watch)
