The power relationship between the computer and the human has shifted since then. We want our computers to run slower so we don’t feel quite so inferior.
Anyway, if you really want to, you can emulate old OSs with a very fast modern computer. Some emulators even bridge the network and file system to support enough that you can really live in it.
It's not just me who prefers everything as fast as possible, but true of people in general. Google measured that slowing down loading a search page by only 400ms caused people to do fewer searches. And the biggest reason I heard people say they switched to Chrome was that it was faster than other browsers (which was true for the first couple years after release).
