I was thinking that people championing and rejecting these practices was more a telltale sign that we don't understand them than anything inherently wrong with disliking things. So wrt pushups, it's as if millions of people were saying, "pushups don't work" and millions of others were saying, "pushups made me strong." I think if we solve the problem of understanding why these things sometimes work, we will discover some deeper, more important thing. Maybe pair programming isn't about pairing at all, maybe it's really that we suck so bad at code review, and "soling" pair programming will actually make it obsolete. I don't know, but as they say, "The best way to predict the future is to invent it."
