Optimization of dynamic typing can go pretty far AFAIK.  In an ideal
case, type-checks are hoisted to outside critical sections of code and
don't affect the speed of e.g. a tight loop.  And then there's JIT and
all that jazz...

Users of languages with good static type systems like ML and Miranda
descendants would rather argue that types make the program more
maintainable, and aren't too much of a bother since they're inferred in
many common cases.  Not my own experience, but I have no reason for a
wholesale disbelief against them (only skepticism on *how* great static
typing is).

Using high-level/dynamically-typed, and low-level/statically-typed as
synonyms seems pretty wrong.  There are very low-level dynamically typed
languages (Forth), and very high-level statically typed ones (Haskell).
