There's a difference between hurtling forward on momentum and having
functioning engines. Just because a chicken runs around for a while
after losing it's head doesn't mean that headless chickens are viable.

If the plane is flying then it's tautology. If you're saying that the
plane could fly at any time then you are eliminating the possibility
that it can't fly. You're just saying 'suppose I build a brain that
acts just like a conscious brain in every possible way...is it
conscious?' To which I'm saying, the brain will probably not act like
a brain unless it's made of living biological organisms, and even if
it appeared to act that way, it will probably not feel like a person,
it will feel like math. You're wanting to make consciousness into a
function of calculation, but it's not, it's a function of awareness,
which is sense, which is detection, which is 1p physical experience.
Calculation is a function of consciousness. It's a high level
function. The psychic equivalent of plastic - a feeling of simulated
non-feeling used to represent sequences abstractly. They can't replace
feeling because they are based on feeling and not the other way
around. Even a computer does not compute. It's just physical materials
responding to changes in it's environment. It's only us who know that
it's computing for us.

Fire isn't in the log, but you can approximate a burning log to some
degree with concrete log and burning gas. It's not a log but it is
fire in the fireplace. If I turn on cable TV around Christmas, they
run a video of a log burning. That also is not a log, and it's not
fire, but it emulates a visual sense of the thing.
So, in the same way, you can have a program running a YouTube of a
person, which is like my TV log, you can have a really great android
brain made out of silicon and plastic which maybe gets you to the
concrete log, provided that you are connected to a gas utility or
propane tank - which *would* have to be organic and combustible. Maybe
nanobot neurons burning glucose would be enough to sustain a spark and
give you a proper Disneyland level animatronic simulation of a person.
Still, it's not burning wood, so it's not really the same thing.
Think of how fragile human consciousness is - we don't need to replace
our entire brain with plastic to become a zombie. We can just play
computer games for a few hours, or get addicted to gambling or meth. A
strong conk on the head could do it.

My hypothesis asserts that.

To be more clear, I don't think that chlorophyll can sense what it is
directly, much like we could not guess what we look like without
mirrors, reflections, photos, etc. It's more like everything can sense
what it's world is. We need a brain to know that our body's stomach is
hungry, but the stomach doesn't need the brain to know that. A lot of
organisms (like starfish) don't have 'brains' and get along perfectly

Right. I agree. I think of consciousness (loosely) as awareness of
awareness, awareness as sense of sense, sense as detection of
detection. Consciousness implies abstract self-representation. A
molecule like chlorophyll is only elaborated to the detection level,
but it brings a new level of flexibility (like carbon does for organic
chemistry) that forms the building blocks of an organism that can
sense more than the molecular sum of it's parts.
> What makes you sure that my brain has any idea who I am?
That's true, your brain has no idea who you are. Which is why if you
build something which is merely like what the brain appears to be, it
won't be able to host a phenomenon who knows who it is.

Infinities are an abstraction. A pattern of pattern-ness, and pattern
can only be expressed through a finite medium. You can't literally
realize infinity, you can only gesture toward it. It's the "..."
beyond which you can only change the subject. Consciousness is
awareness reaching toward infinity, toward abstraction, toward self-
realization through self-negation. Awareness is finite though, it's
just not computable because it's qualitative and experiential. We're
at a disadvantage to understand what we are because what we are, as
intellectual minds, is literally the intention of something physical
to be unlike anything physical.
