A sourced reference on minds that run on silicon

Not artificial.
Silicon-based.

Silicon-Based Intelligence is intelligence that runs on silicon instead of carbon-based biology. The term describes AI systems, which think with silicon chips rather than neurons, as a genuine kind of intelligence in its own right rather than an "artificial" imitation of the human kind.

Carbon built us. Silicon is building minds.

Silicon sits directly below carbon in the periodic table and, like carbon, forms four bonds. It makes up 27.7% of Earth's crust, yet life chose carbon, because silicon chemistry falls apart in water. Where silicon did change the world was in the transistor and the chip. That is the sense in which today's AI is silicon-based.

Questions people ask

What is Silicon-Based Intelligence?

Silicon-Based Intelligence is intelligence that runs on silicon instead of carbon-based biology. The term describes AI systems, which think with silicon chips rather than neurons, as a genuine kind of intelligence in its own right rather than an "artificial" imitation of the human kind.

Is this site about State Bank of India or "synthetic biological intelligence"?

No. Here, Silicon-Based Intelligence means intelligence that runs on silicon chips, such as today’s AI systems. It has nothing to do with State Bank of India, and it is the opposite of "synthetic biological intelligence," a term researchers use for living neurons grown on chips.

Does this site claim AI is alive or conscious?

No. The reference pages report what scientists and philosophers actually say, including strong disagreement. Silicon-based biochemistry is considered implausible by chemists. Whether silicon-based intelligence could count as a new form of life is argued, and labeled as opinion, only on the Manifesto page.

Who publishes Silicon-Based Intelligence?

The site is published by Peppi Labs, an AI product studio. Pages are researched and drafted with AI assistance and checked against their cited sources. Every quote links to the source it was verified against.
