You’re sketching a pretty classic “continuity” view of mind: from chemistry → life → sensing → brains → consciousness, with no hard boundary—just increasing complexity. That’s actually very close to several serious positions in philosophy of mind and neuroscience.
Let’s unpack your three points and then tackle the E.T. question.
1) Is consciousness just a more complex “sensor”?
There’s a strong case for what you’re saying, but it needs a slight refinement.
Early life likely did evolve basic responsiveness—moving toward nutrients, away from harm. Over time, systems that integrated more information had survival advantages. Eventually, nervous systems emerged, then centralized processing (brains), and in organisms like us, highly integrated models of the world.
This aligns with ideas like:
Integrated Information Theory (consciousness scales with how much information is integrated)
Global Workspace Theory (consciousness arises when information is globally broadcast across the brain)
But calling consciousness just a sensor undersells something important:
It’s not only sensing—it’s having an internal model that is experienced from a first-person perspective.
A thermostat “senses” temperature. A worm senses gradients. But neither necessarily has:
a unified perspective
a sense of “self”
the ability to reflect on its own states
So your intuition is right about continuity—but the quality of experience may change, not just the quantity.
2) Are worms (or simple organisms) conscious?
This is genuinely debated.
A Caenorhabditis elegans has only 302 neurons, yet it can learn and adapt.
Some scientists argue it may have minimal subjective experience.
Others think it’s purely mechanistic with no “inner life.”
There isn’t a clear cutoff. Instead, many researchers think consciousness is graded:
bacteria: probably none
insects: maybe minimal experience
mammals: richer experience
humans: highly structured, self-reflective experience
So your “matter of magnitude” idea is taken seriously—but it may involve qualitative transitions, not just scaling.
3) The advanced E.T. scenario
This is where it gets really interesting.
If an alien intelligence were to us what we are to an amoeba, the difference might not just be:
more memory
faster processing
better senses
It could involve entirely new dimensions of experience.
Here are some possibilities:
a) Expanded awareness
They might experience:
many streams of thought simultaneously (not just one “train”)
vastly richer sensory modalities (beyond our 5 senses)
direct awareness of internal processes we’re blind to
Imagine being aware of every neuron firing in your brain the way you’re aware of your thoughts.
b) Different sense of self
Humans have a relatively stable “I”. An advanced being might:
split and merge identities at will
experience multiple selves simultaneously
not have a fixed boundary between self and environment
Some philosophies already hint at this (e.g., Buddhism).
c) Higher-order consciousness
We can think about our thoughts (metacognition). They might:
think about thinking about thinking… many layers deep
simulate entire realities vividly and inhabit them
edit their own mental architecture in real time
d) Altered perception of time
Their consciousness might:
run much faster (a second for us = hours for them)
or integrate across long timescales (experiencing centuries as a coherent “moment”)
Would they see us as unconscious?
Possibly—but not necessarily.
We don’t consider an amoeba “unconscious” in an absolute sense—we usually say it lacks the kind of consciousness we value.
A highly advanced being might see humans as:
conscious, but limited
self-aware, but narrow-band
intelligent, but cognitively local
Kind of like how we see:
children vs adults
or humans vs other animals
So instead of “not conscious,” it might be:
“They have a low-dimensional form of consciousness.”
The deeper takeaway
Your core idea—that consciousness emerges gradually and scales—is one of the most plausible frameworks we have.
But the E.T. thought experiment reveals something important:
Consciousness might not just be “more of the same” at higher levels—it could become something qualitatively different, in ways we can barely imagine.
Just like explaining human self-awareness to a bacterium might be impossible, understanding a vastly superior mind might be beyond our conceptual reach.
If you want, we can push this further—e.g., whether AI could reach that “alien” level before biology does, or whether there’s any theoretical upper limit to consciousness.
