> Thus, the stringing-together bit is far, far less complex.
This is the statement I disagree with the most.
The problem is that combining different programs, that aren't strictly written to interoperate in a specific way, gives you an order of magnitude increase in the complexity. Sure, running find and grep together is common enough, but how about running {obscure_command_rarely_used} through {other_command} through {other_other_command}. There are always corner cases that can crop up, and even before we get to corner cases, just understanding how to fit the pieces together correctly is not so simple.
One cohesive program designed to all work together sometimes just makes more sense, especially when we're talking about complicated, high level actions, as opposed to the more common low-level actions of unix commands. (Or well, maybe high level and low level is the wrong way to put it - maybe the lower abstraction stuff in Word vs. the higher abstraction stuff that Unix tools deal with.)

Yes, your example of find|grep is perfect for this. Sometimes (not often) I have a situation where a simple pipe combination doesn’t work and I have to fall back to awk, which would be the single cohesive (and more complicated ) program.
