"With few exceptions (such as parsers), unit tests are a waste of time."
I was in full agreement aside from this. Unit tests are more than just a substitute for static typing.

A parser is a discrete chunk of code that's general-purpose (likely to be called from lots of places with different content), but with a fairly straightforward list of cases that you can/should test to see how correct and robust it is.
There's a lot of code that fits into this category; not just parsers.
