We write software for humans. The same humans who can't tell the difference between instantaneous events and events separated by less than a few milliseconds. The same humans who won't be around for long enough to recognize the difference between a really large number of events and an unlimited number of events.

So, by all means, continue to write software for those ideal beings that live in a world of comprehensible instantaneous and unlimited events, but you'll find that most people on this forum are operating under a different assumption.
