Allan Kay on Computing
"If business users were less shortsighted, Kay says, they would seek to create computer models of their companies and constantly simulate potential changes. But the computers most business people use today are not suited for that. That's because, he says, today's PC is too dedicated to replicating earlier tools, like ink and paper. "[The PC] has a slightly better erase function but it isn't as nice to look at as a printed thing. The chances that in the last week or year or month you've used the computer to simulate some interesting idea is zero—but that's what it's for." "
computer's are about simulating ideas and systems, then seeing how new ideas/changes would effect those systems :)
