You forget the machine structure. A Wright Flyer is a new machine structure. A
programmed computer is not.

I can't tell if you're pretending to be stupid, or demonstrating the real thing.
Your blind
persistence in pushing an obviously invalid analogy
gets....wearing. But, since you insist:
Define all the properties of
wood, and enumerate every possible value for each one.
Then do the same for
canvas, rope, pulleys, and all the other materials used to make
the Flyer.
Then define and enumerate all possible ways they can be combined. Go
ahead 
if the analogy were valid, it could be done.
Of course, you can't do
it. Nobody even knows all the properties of any of the materials,
or all the
values for the ones we do know about, or all the possible ways they could
be
combined. There are billions of possible values for "a wooden strut 75 cm
+/ 5mm in
length". Every tree grows differently. Every pulley is made out
of inexact parts.
On the other hand, we CAN demonstrate,
mathematically, that every possible state
of a computer can be enumerated,
and specify a procedure by which this task can be
accomplished. Why? Because
while the computer is also constructed of materials
having many complex
properties, the circuits are carefully designed to compensate for
variations
in material and construction, and to precisely express the values of bits.
The
computer is deliberately limited so that it can do nothing
else.
A bit is an artificially created abstract entity that has exactly
one property, with the
mutually exclusive values of 0 and 1. Giving a bit a
value of 0 is trivial and obvious. Giving
a bit a value of 1 is trivial and
obvious. Giving two bits a value of 00, 01, 10 or 11 is trivial
and obvious.
Giving 3 bits a value of 000, 001, 010, 011, 100, 101, 110 or 111 is trivial
and
obvious. Setting any finite number of bits to any of their possible
states is trivial and obvious.
Enumerating all possible combinations of any
finite number of bits is trivial and obvious. There
is no possibility of
uncertainty, ambiguity, indeterminate or unexpected results; such things
are
precluded by the definition of "bit", and any deviation from exact deterministic
behavior
is an error, and outside the scope of the computer's intended
purpose.
On the day that a computer is built, it is capable of running
any program that will fit within the
constraints of its hardware. Setting a
bit, or a million bits, or ten billion bits to a specific state
to make some
particular use of that capability is an obvious operation trivially derived from
the
computer's design, and does not change its function or purpose in any
way.
