I was watching Halt and Catch Fire and in the first season the engineering team makes a great effort to meet something called the "Doherty Threshold" to keep the responsiveness of the machine so the user doesn't get frustrated and lose interest. I guess that is lost to time!
I have a 2015 MacBook Air I abandoned recently for being so painfully slow to use that I had almost not touched it for months. I have an iPad Air 2 that is basically unusable at this point. Both are 2-3 orders of magnitudes faster than those old computers that work instantly.
But windows and web apps are super slow now too
Think of all the landfills and wasted work hours earning the money needed to fill those landfills. The heavy and rare metals
This is proof that if computers were 10x faster, they would run slower than ours today, because in the past we’ve seen that be true over and over. The software companies will just make heavier and heavier programs and operating systems until we have gained nothing but a significant amount of co2 emissions
Give it some time for the industry to finally mature.
