In my view, we got past the "sweet spot" for personal computers for a while. Even the most affordable computers (mobile devices included) can easily render a nice UI in a resolution high enough for our eyes to perceive as "great", and provide the same user experience than high end devices 99% of the time.
And then we have capitalism... companies that make those devices and their software are having a hard time convincing the end user to buy their new stuff. Putting very low "minimum specifications" is also part of the plan: They allow you to install brand new software on weaker systems just for you to see how badly it runs in your outdated machine , making you consider an upgrade.
To add insult to injury, the technology industry makes a lot of money from our data. So along with the usual software bloat, we also have an overhead for having each action we make associated to an user account being sent to some server for whatever reason (in other words, you brand new hardware is working against you 😁). And I totally agree with what other users said here... in such times of pandemic this is just disgusting.
Even if you are a PC gamer the situation is kinda similar (even worse, maybe?), you basically need exponentially more powerful hardware to have logarithmic gains. I remember seeing a video from NVIDIA a few days back explaining how much better 240hz are compared to 60hz, showing some examples in very slow motion to explain concepts like input delay, ghosting and screen tearing. That's all true, but they "forgot" mentioning you need 4x the computing power to run a game in 240fps to be able see such minimal gains.
Same thing with resolutions. The difference between 4k and 2k is not worth the 4x extra computing power required. Much less worth the 16x extra computing power required for 8k (and no, I don't consider upscaling as being a justifiable reason for such screens).
Holy crap, if you want true 8k@240fps you need 64x more power! How does it make any sense?! To play a game in 2k@60fps you need one computer, but then you need to buy another 63 similar computers to play the same game, with the same graphical effects, but at 8k@240fps.
