This is my frustration with Apple's policy of dropping support for hardware in MacOS. It made sense in the 90's to upgrade every 2-3 years because you got 1.5-3x more performance each time. So 6 year old hardware was almost an order of magnitude less capable.

Fast-forwarding to today, a "legacy" 10 year old ("Mid-2011") MacBook Pro supports just as much memory (16GB) as Apple's current M1 offerings. The M1 does put up some very impressive numbers on the single-thread CPU front, but that's because we've gotten used to such small progress every year--it's only about 2x the speed of the 2011 MBP for single thread tasks.

You still get that level of performance increase. It's just that it's to the point of being imperceptible, or invisible, to the vast majority of users. The only ones who really notice are the ones really pushing the machines with things like 3d rendering, 12k video production, and high end audio (I can run 80 plugins now where I could only run 70 before!).

Texting? Doesn't matter how fast your machine gets, you won't notice. It will perceivably perform just as good as a phone that texted 20 years ago. You can run benchmarks and see, oh yeah, this is faster, but it's not noticeably faster to your human inputs.

In the days of 300 baud modems, they were so slow you could actually read text as it was sent over the line, as if someone was just a very fast typist and you were watching them. Now, you get full multiple pages of text with videos that pop up almost instantaneously. Once we got to 1200 baud, it was too fast to read as it was coming over the line. You couldn't catch up. Ever since that threshold was crossed, it doesn't matter how fast speeds get, they're all faster than the human brain can absorb so they are basically the same in our minds.

Except for the web. Which seems to get slower and slower due to bloat and overload, no matter your computer or internet speed.
Isn't the corollary then, that if we didn't upgrade our computers, the web would get faster, or at least not get any slower?
