Certainly, it would be beneficial for people who buy chess programs to learn
about hash tables and resign factors and things like that.

Still, I think it absurd to think that someone who walks into a retail store
will bother to learn what parameters like those mean.  These things are
interesting to persons of a certain bent who are very rare.

You did not understand my illustration about the horse.  My point was that most
people don't know what those terms meant or how to accomplish the goal.  Of the
group that do not know them, only a small fraction will care to learn them.

There are 5 million people who have bought ChessMaster.  I am guessing that
4,990,000 of them have NO IDEA what a hash table is.  Probabbly about one
million of them use the product regularly (e.g. once per month or more).  Very
very few people will need to know technical things to use and enjoy the product.
 Sure, if they want to learn intricacies they might enjoy it even more.  In the
same way, most people cannot tell you what a good valve clearance for their
engine is, or why the spark ignites the gasoline before top dead center.  But
they can still enjoy and drive the car, even without knowing how to tune it up.

I am not disagreeing that it is better to learn.  I am saying that most people
won't care about all those parameters we spent weeks fussing over and it is not
a defect on their part, any more than not knowing the compression ratio of your
car's engine is a defect in the driver.
