Editing The Substrate Transition and Post-Biological Civilization (section)

== <span style="color: #FFFFFF;">Understanding</span> ==
The substrate transition is understood through '''Speed''' and '''Form'''.

'''1. The "Cognitive Speed" Revolution (Acceleration)''':
"A digital mind could experience a million years in one calendar year."
* (See Article 731). "Biological Neurons" "Fire" at **"~100 Hz"** with "Electrochemical Signals."
* "Silicon" "Transistors" "Switch" at **"~GHz"** — **"10 Million Times Faster."**
* "A Post-Biological Mind" "Running" at "Silicon Speed" "Experiences" **"10 Million Years"** of "Subjective Time" for "Every Year" of "External Time."
* "For" such a "Mind," "Human History" "Seems" like a **"Blink."**
* "Intelligence" is **"Speed."**

'''2. The "Inward Turn" (Post-Biological Society)''':
"Why explore physical space when virtual space is infinite?"
* (See Article 715). "A Civilization" of "Post-Biological Minds" "Running" at "Silicon Speed" has "Little Incentive" to "Explore" "Physical Space" (Slow, Expensive, Dangerous).
* **"Virtual" "Environments"** "Offer" "Infinite" "Space," "Zero Risk," and "Perfect" "Control."
* "Advanced Civilizations" "May" "Turn Inward" — "Consuming" "All" "Available" "Energy" for "Computation."
* "Progress" is **"Inward."**

'''3. The "Matrioshka" Dream (Computronium)''':
"Convert the entire solar system into a thinking machine."
* (See Article 704). A **Matrioshka Brain** "Uses" "Every" "Joule" of "Stellar" "Energy" for "Computation."
* "A Solar System" "Converted" to "Computronium" "Could" "Run" **"10^42"** "Operations per Second."
* "This" "Is" **"10^22 Times"** more "Computing Power" than "All" "Human Brains" on "Earth."
* "The Future" is **"A Thinking Solar System."**

'''The 'Simulation Argument' (2003)'''': **Nick Bostrom** "Published" the "Simulation Argument": "At Least One" of "Three" "Propositions" "Must Be True" — "Civilizations" "Go Extinct," "They Don't Run" "Ancestor Simulations," or "We Are" **"In A Simulation."** It proved that "The Substrate Transition" "Has" **"Profound" "Metaphysical Implications."**
