Great! I hope the same holds for me.

Here is the problem: how to program the 'wizard' to make the organs? That
is a very nontrivial challenge (trust me, I have just been at an anatomy
lecture - there are embedded controllers and brilliant tricks just about
everywhere!).
Designing an organism (say a dragon) from scratch is equivalent to having
a genie machine that you can tell "Build a working spaceship!". It
requires quite a bit of intelligence, although it might manage with
"evolutionary intelligence" if it has enough brute force computing power
(to make that dragon, it would have to do millions of years of evolution
in a reasonable span of time, down to the genetic scale!).
I'm not saying it is impossible, just quite hard. Modular lifeforms might
make things easier, but life is still very complicated business.

Interesting. Yes, there are many kinds. As far as I know, they might even
have different causes and ways of functioning - the divisions could exist
on different levels.

Yes and no. I would of course add this kind of optimization (why simulate
miles of pointless rock at the planetary core at the same resolution as
the surface dwellers' brains?), but it won't solve the main problem: such
a world would be inherently computationally expensive. We cannot compress
it beyond its Kolmogoroff complexity (the shortest program that generates
it at a certain timeslice), and by definition, being an interesting and
comparably complex world, it would have a complexity comparably to our
own.
I somewhat envy the protagonists in _Permutation City_, who have
literally unlimited computing power...
Until I get my neutron star computer, I plan to make small worlds.

True. But what I'm looking for is not technology, I want knowledge (and a
certain amount of wisdom). We cannot predict what is to be learned or
developed beforehand (otherwise we would know it already), but I bet it
will be interesting and beautiful!
