Not really peaked. More like we entered the era of diminishing returns which btw is great if you are not blinded by the marketing. Mid to low range phones are fairly cheap and more than adequate for almost anything . Do you know how shit even mid range phones were 10+ years ago and how fast they were getting too old to be usable. Right now its more than reasonable to use any smartphone for a 3 to 5 years and probably even longer ( before only champions like samsung Galaxy note 4 could even hope to match that ). Everything you talk about is cheaper and more afforable than ever before( if you do the usual and not buy overpriced brands beacuse of a brand like apple , galaxy phone , roomba robot vacuums etc... ). The only thing thats a shitshow right now are websites and computer prices precisly beacuse right now the current hype is LLM( which makes graphic cards really f expensive and kinda hits website by ricoshet due to the negative LLM influence ).

Actually even as smartphones go there is a progress. Folding phones. Coincidently they are less relaiable and not as long lived . Exatcly as smartphones were 10 years ago.

Also smartphones were something much grander than a simple tech innovation. They were truly a society changing innovation like cars, trains , planes or a computer. They just peaked much faster than cars , trains or planes. In fact they probably had bigger impact on society than computers.
