Now this is artificial intelligence at work.

The program monitors people's habits for a couple of weeks, quietly making decisions based on what it has "learned." A couple of weeks after installation, for example, the program might determine that a worker rarely responds to certain bulk e-mail from the human resources department, and so those e-mails would receive low-priority placement. In theory, the longer the software is in use, the more precise it becomes at prioritizing.

One of the ironies of computing is that, even though it is supposed to be a time
and labor saving device, computers require time and labor invested if you want
to be productive. E-mail, a great time saving invention, occupies too much
of our time. Writing and customizing a filter would solve that problem, but it
takes time to customize the filter. So now, there are self-customizing filters
that will adapt to your habits.
