Hello,
I believe that there are great thougths in this mail.However, I will try to
enhance it, because there are some major mistakes.

Please see : http://www.haskell.org/arrows/
Arrows are a new abstract view of computation, defined by John Hughes [Hug00].
They serve much the same purpose as monads -- providing a common structure
for libraries -- but are more general. In particular they allow notions of
computation that may be partially static (independent of the input) or may
take multiple inputs. If your application works fine with monads, you might
as well stick with them. But if you're using a structure that's very like a
monad, but isn't one, maybe it's an arrow.

Please see :
http://www.dcs.st-and.ac.uk/~eb/esc.php
ESC, the Epigram Supercombinator Compiler, is a simple functional language
which compiles to efficient (well, maybe!) C code. The primary aim is to
develop a back end for Epigram, but it will (I hope, eventually) be useful to
anyone looking for a back end for a functional language.

jhc
jhc is a haskell compiler which aims to produce the most efficient programs
possible via whole program analysis and other optimizations

You don't need 6 languages ! 1 will be enough :
http://programatica.cs.pdx.edu/House/
Haskell User's Operating System and Environment, version 0.8, August 2006
House is a demo of software written in Haskell, running in a standalone
environment. It is a system than can serve as a platform for exploring
various ideas relating to low-level and system-level programming in a
high-level functional language. More details are available in our ICFP 2005
paper: A Principled Approach to Operating System Construction in Haskell.

I believe that FPGAs will be better :

http://www.openfpga.org/
>None of these systems is yet complete:
There are almost complete and FPGAs are available ;) !
I look forward to your answer,
Best Regards,

PS : I believe that we are near a fomally verified AI :
-Separation Logic :

http://en.wikipedia.org/wiki/Separation_logic
Separation Logic a term attributed to John C. Reynolds, is an extension of
Hoare logic that describes variations on program logic in computer science.
In particular, separation logic facilitates reasoning about:
programs that manipulate pointer data structures — including information
hiding in the presence of pointers;
"transfer of ownership" (avoidance of semantic frame axioms); and
virtual separation (modular reasoning) between concurrent modules

Towards Planning as Concurrency
Ozan Kahramanogullari
We present a purely logical framework to planning where we bring the
sequential and parallel composition in the plans to the same level, as in
process algebras. The problem of expressing causality, which is very
challenging for common logics and traditional deductive systems, is solved by
resorting to a recently developed extension of multiplicative exponential
linear logic with a self-dual, noncommutative operator. We present an
encoding of the conjunctive planning problems in this logic, and provide a
constructive soundness and completeness result. We argue that this work is
the first, but crucial, step of a uniform deductive formalism that connects
planning and concurrency inside a common language, and allow to transfer
methods from concurrency to planning.
