Here's a transcript of the podcast I believe Kent is referring to. Judge for yourself whether Joel "makes comments that make clear his lack of knowledge".

I'd like to see Kent respond to Joel's specific points. E.g:

  The real problem with unit tests as I've discovered is that the type of changes 
  that you tend to make as code evolves tend to break a constant percentage
  of your unit tests.... 
  So the end result is that, as your project gets bigger and bigger, if you 
  really have a lot of unit tests, the amount of investment you'll have to make
  in maintaining those unit tests, keeping them up-to-date and keeping them 
  passing, starts to become disproportional to the amount of benefit that you 
  get out of them.
