Will you need to use a software agent? You probably will. Why, not the least because others do.

In time-sensitive task organized on a "first come, first served principle" (say, buying a concert ticket, signing up your kids for a popular course, etc), you will compete against software agents, who are not only much faster in completing the task, but also capable seeing the task the second it appears.

You've probably already been competing against knowledgeable programmers who have written scripts and cronjobs for such tasks for a long time.

But now, the exception becomes the rule.

Which probably kills the first come, first serve principle for deciding how distribute rare goods.
