View source for Silicon-based Life Form

==Full Title or Meme==
A [[Silicon-based Life Form]] is a real-world entity, or artificial intelligence, that may even have legal standing in a jurisdiction.
==Context==
* The term Silicon-based comes from the common constituent of the chips that make up computing machines on which artificial intelligence instances operate.

==Artificial Life==
The first attempts an creating artificial life was the Mechanical Turk, a fraud perpetrated in the 1850's showed a mechanized contraption that was claimrd could play chess.<ref>Tom Standage. The Turk: The Life and Times of the Famous 19th Century Chess-Playing Machine. (2002-04-01) Walker. ISBN 978-0-8027-1391-9</ref> Machines that could emulate a variety of animal functions have been popular for centuries. On in the twentieth century was an attempt to understand life by looking at fully artificial emulations even possible.

<blockquote>You insist that there is something a machine cannot do. If you tell me precisely what it is a machine cannot do, then I can always make a machine that will do just that.  -- John von Neumann</blockquote>

In 1951 the very early years of the digital computer John von Neumann invited  Nils Barricelli<ref>Freeman J. Dyson, ''Biology at the Institute for Advanced Study''  (2008) https://www.ias.edu/ideas/2008/dyson-biology</ref>  "for two terms. Using the computer that von Neumann had built at the Institute for Advanced Study, Barricelli simulated the evolution of populations of artificial organisms. Each organism was represented by a genome consisting of a string of numbers. Random mutations and sexual exchange of genes caused populations to evolve. Barricelli observed the phenomena of speciation, parasitism, and predation arising spontaneously in his computer runs. He also observed punctuated equilibrium, the tendency of dominant species to remain static for many generations and then suddenly give way to new dominant species of a different character. He was a pioneer of the new science of Artificial Life, forty years before it became fashionable. With astonishing ingenuity he was able to simulate sophisticated evolutionary processes on a machine with a total memory of four kilobytes."

===von Neumann Probe===
A Von Neumann probe is a self-reproducing intelligent device with interstellar capabilities. A space-faring civilization could conceivably use such constructs to occupy much or all of the Milky Way galaxy and perhaps the entire universe. This paper presents several reasons that a civilization might decide to produce and deploy Von Neumann probes. Physically possible interstellar propulsion methods for such devices are discussed, as is a launch strategy minimizing the duration of an interstellar transfer. Various solar system locations could be investigated to determine whether Von Neumann probes are present in our vicinity.<ref>Gregory L. Maloff ''Von Neumann probes: rationale, propulsion, interstellar transfer timing'' (2022-02-08) https://www.cambridge.org/core/journals/international-journal-of-astrobiology/article/abs/von-neumann-probes-rationale-propulsion-interstellar-transfer-timing/5202679D74645D3707248FE5D5FA0124</ref> Perhaps the Unidentified Flying Objects seen from time to time are just such probes collecting sufficient material to build another clone. Perhaps von Neumann underestimated the sophisticated infrastructure needed to produce devices capable of [[Artificial Intelligence]].
