Based on your comment, you basically agree with Steve's argument. You agree with him that "grilling" and "role playing" don't work. This is precisely what he meant. He then goes on to argue that people should build products that they want for themselves. You want people who build products to "live [their users'] lives" in order to understand the users' tasks. Sounds quite similar to me.
