Indeed, the essence of your criticism seems to be merely that
Mathematica gives a slightly different technical meaning to the English
word 'List' than that of Lisp!

If the head of a Mathematica list was LinkedList, you might have a
point, as it is, your criticism is absurd. I might as well claim that
either the physics concept of field or the pure maths concept of a field
is wrong because they are not the same!

If anything, Mathematica's use of the term 'List' is a little closer to
its English meaning, in as much as you can access its elements in random
order - just as you can with a shopping list!

John McCarthy didn't get to coin the computer science meaning of the
word 'List' for ever more! Indeed, perhaps the very fact that he chose
the word 'List', rather than something more descriptive like 'Chain'
meant that he wanted people to concentrate on what it represented,
rather than just on how it was implemented.
