>Regardless of OS, they all seem extremely fast, and feel faster and faster as time goes on.
One analogy is that the distance between two places in the world hasn't changed, but we're not arriving significantly faster than we before modern jetliners were invented. There was a period of new technology followed by rapid incremental progress toward shortened travel times until it leveled off.
However, the number of people able to consistently travel between more places in the world has continued to increase. New airports open regularly, and airliners have been optimized to fit more people, at the cost of passenger comfort.
Similarly, computers, operating systems, and their software aren't aligned in optimizing for user experience. Until a certain point, user interactions on MacOS took highest priority, which is why a single or dual core Mac felt more responsive than today, despite the capabilities and total work capacity of new Macs being orders of magnitude higher.
So we're not really even asking for the equivalent of faster jet planes, here, just wistfully remembering when we didn't need to arrive hours early to wait in lines and have to undress to get through security. Eventually all of us who remember the old era will be gone, and the next people will yearn for something that has changed from the experiences they shared.
