luca

The "PHI" software once it is designed will have to be put into practice. I'm looking for the most primitive form of life. I can stop at what is called "progenitor" or LUCA. PHI is ultimately designed to support a life form and I should be able to demonstrate credibly that software is capable of it, at least theoretically.

The concept of a last universal common ancestor of all cells (LUCA, or the progenote) is central to the study of early evolution and life's origin. Yet information about how and where LUCA lived is lacking. LUCA is seen as being anaerobic, CO2-fixing, H2-dependent with a Wood–Ljungdahl pathway, N2-fixing and thermophilic. LUCA inhabited a geochemically active environment rich in H2, CO2 and iron. The data support the theory of an autotrophic origin of life involving the Wood–Ljungdahl pathway in a hydrothermal setting (WEISS 2016).

I will try to imagine the LUCA universe, that is, the natural environment with which this microorganism was in contact. In that LUCA universe simulated on my computer I will have to recreate a being like LUCA. The simulation will want to be demonstrative and I can not afford to reproduce exactly all the conditions of LUCA's microuniverse. Every being has certain attributes, common to other beings. Also, the artificial organism "LUCA" has the ultimate goal of continuing its evolution immediately after any recurrent event and for this it must know everything that appears externally, potentially. Any damage as a result of confrontation with the outside will be remedied, will be remedied by multiplying it. Eventually, hypothetically, it will have to encompass the external universe, which will become an internal universe. All these functions can be simulated on a computer.

So we have a LUCA INDIVIDUALIZATION and then his ANIMATION, by establishing the links between his structures. Here we can not communicate with the subject, but we apply the pattern of being to what is LUCA. The Artificial Body will follow the procedures of a kind of software code that will allow it to survive. The result will not be a clone containing all the genetic material, but a software product, a one that can react as a subject and more one that can be eternal.

Okay, I know that! Even, ”a glassware cabinet is a computational nightmare” (BRIAN 2011). And then what will be a computer program that tries to simulate a living being and more than that, a man ? But we start with the least, with the simplest possible being, with LUCA.

LUCA Physiology: anaerobic, CO2-fixing, H2-dependent with a Wood–Ljungdahl pathway, N2-fixing and thermophilic (WEISS 2016)

Here I try to make a schema of the habitat and physiology of the last universal common ancestor.

The virtual reconstruction will be done after the completion of the INDIVIDUALIZATION process. For this I gather the perceptible data on all observable objects, on the external environment and on the physiology of LUCA. After this first step, I will assign a motive function (ANIMATION) to the progenote. This function will depend on what LUCA is and the universal functions of any form of life, the ultimate goal of life. This "ultimate goal" is linked inter alia to perpetual continuity and a desire to encompass everything, as the progenote universe allows.

”A bounded optimal (a.n. kind of AI) agent must adapt to the environment in which it finds itself, so that eventually its internal organization will reflect optimizations that are specific to the particular environment.” ( RUSSELL 974 ). This is a true prophecy. The artificial organism tries to reflect its entire environment within itself, for that is the only way to ensure its optimal continuity. Then this inner universe must be functional to predict the results of action on it as a reaction.

Adaptation is now seen as the adjustment or changes in behavior, physiology, and structure of an organism to become more suited to an environment. According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation. However, adaptation has a much more intimate structure and does not involve random mutations, but self-induced mutations, and not as abandonment in the environment, but with ultimate goal, adapting the environment to Self. The so-called "Artificial Intelligence," however technically is the term, must also receive a change of perspective for success in creating an artificial organism. The whole world will be conceptualized in the inner universe of the subject, and the concept will receive a determined value (INDIVIDUALIZATION). This internal world will then be put into operation (ANIMATION). It is not so difficult, as social practice seeks to accumulate knowledge of the being for thousands of years. And somehow managed to get to an end. I personally added nothing new, but I only systematized this knowledge.

Practical issues: After finalizing the theoretical part, a rather philosophical one, I accept that there is still a long way to finishing a software (PHI). A first timid step in programming now allows me to work, although not my specialty, at an attempt to simulate "psychic life" (the soul can say). For this we took the C ++ code of the snake game. I try to put into the software the four generic principles seen as the purpose of being (eternity, contentment, sense and connection of everything) and establishing a link between the "memorized" elements using the 10x10 sense palette (feelings because these are the bricks of psychic life). The snake, without the help of a user, has to search for the apples (good) and avoid the danger, stone (bad). Apples grow its size, for he wants to embrace everything (connection) and for this he has to see everything. As the negative elements diminish from the size, he will have to bypass them. The snake must have sensors for the senses (a radar), a head (the skull that will remain after its death). The external environment will be implanted in that three elements (apples, stones and air with neutral value) will be randomly displayed at the push of a button. The button can be operated once in 1 minute. If he does not eat anything for 10 minutes, the snake loses one segment at 1 minute until it dies. After reaching 10 segments, the snake divides into 2 pieces. This would be the smallest imagined dimension of the universe. The level reached by the artificial intelligence must allow me this simulation. Think I will succeed! - 311018

UPDATE: There are too few elements to simulate. I have to try a more complex version of the environment. - 03/07/2019
