Next time on Hacker News: an article about the economics of strong typing, with someone threatening to quit if they have to use a strong typing system, demanding that be factored into the economics as well.
Perhaps true, but not really the point the authors were looking at.
If you look at @programminggeek's point without passive-aggressive exaggeration and then at the wiki, you'll see that it's specifically called out as a potential problem.
Sadly, it's dismissed out of hand as a "people problem" and "irrelevant". It really deserves more attention.
First of all, if you're looking for programmers to maintain a VB6 app, you really should factor into the economics of that endeavor the fact that most people don't want to code in VB6.
Second, no matter how potentially beneficial the pair programming approach is, there is a question of psychology in play. There are people who are introverted enough that the constant company required for pair programming will wear them down and cause them to quit or change teams. Dismissing it as a "people issue" and misrepresenting it as being unable or unwilling to be a team player is an oversimplification.
