Brave, next future.

Left.Cartoon/Stock.Courtesy. Fun joke.


I have just read 3 articles of the last number of NEJM, related with the employment of progenitors cells derived from bone marrow. The Britons contrarily to Americans or French, have not vetoed their employment. The Englishmen don't accept established jurisprudence in this respect - influenced by ethical valuations - but rather each patient is discussed and treated. In these studies, the progenitors cells are infused directly to the blood or, to the coronary arteries of patients that have suffered acute heart attacks (death of cellular conglomerates). The results are impressive: the heart dead muscle, opens the way to new and vital muscle fibers, reestablishing the affected patient almost completely. This modern procedure like artificial nanocarriers of medications (that arrive to specific affected places) and integrated nanocircuits, each time but small, are configuring an entirely new world, in our own noses, on that but it is worth to meditate. Up to where they will drive us these every time but technological constant changes? did they affect our lives? Will we be overcome by non biological artificial intelligence? when that will happen?...

For Raymond Kurzweil (1948 -), the biological evolution,continues although to linear, slow rhythm. On the contrary the non biological (the technological one) evolution, slips for rails of exponential, continuous growth. The technological evolution follows Gordon Moore's Law (1965) and the Law of the Singularity of Vernor Vinge and Raymond Kurzweil that settles down that in few years, around the 2020 - 2030, the capacity of the integrated circuits, growing from 1965 to the date, twice as much, every 24 hours, they will equal the functional capacity of our brains and few years later, they finished overcoming it. When we are surpassed, in a first moment, we will adapt to this supertechnologies, incorporating them to our organisms, expanding our capacities. Kurzweil senses that nanobots incrusted in our brains, muscles, arteries, etc., will multiply our abilities transforming us into superinteligent cyborgs. They will also prevent us to make sick and they lengthened our lives widely. Nevertheless, some as the prince Carlos from England, believe that the nanomachines when multiplying could destroy the Earth. But Kurzweil assures that nanocounterparts will combat any nanotechnologic disaster and besides the environmental contamination, virus and the poverty : generating foods to will. However, the great nanotechnologic specialization, carry the risk of opening a new space : the terrifying possibility of nanomachines self-replication, that they acquire own conscience and finally decide to get rid of us.

El futuro cercano, que nos espera.

Acabo de leer 3 articulos del ultimo numero del New England Journal of Medicine, relacionados con el empleo de células progenitoras derivadas de la médula osea. Los británicos contrariamente a los americanos o franceses, no han vetado su empleo. Los ingleses no aceptan jurisprudencia establecida al respecto - influenciada por valoraciones éticas- sino que cada paciente es discutido y tratado. En estos estudios, las celulas progenitoras son infundidas directamente al torrente sanguineo o, a las arterias coronarias de pacientes que han sufrido infartos (muerte de conglomerados celulares), cardiacos agudos. Los resultados son impresionantes : el musculo cardiaco muerto, da paso a nuevas y vitales fibras musculares, restableciendo casi completamente al paciente afectado. Este moderno procedimiento al igual que los nanotransportadores artificiales de medicamentos (que arriban al sitio especifico afectado) y los nanocircuitos integrados c/vez mas pequeños, estan configurando un mundo enteramente nuevo, en nuestras propias narices, sobre lo que mas vale reflexionar. ¿Hasta donde nos conduciran estos cada vez mas constantes cambios tecnologicos? ¿afectaran nuestras vidas? Seremos superados por inteligencias artificiales no biologicas? ¿cuando sucedera eso?...

Para Raymond Kurzweil (1948-), la evolucion biologica continua, aunque a ritmo lento, linear. Por el contrario la evolucion no biologica (la tecnologica), se desliza por carriles de crecimiento exponencial, continuo. La evolucion tecnologica sigue la Ley de Gordon Moore (1965) y la Ley de la Singularidad de Vernor Vinge y Raymond Kurzweil, que establece que dentro de pocos años, alrededor del 2020 - 2030, la capacidad de los circuitos integrados, creciendo desde 1965 a la fecha, al doble, cada 24 horas, igualaran la capacidad funcional de nuestros cerebros y pocos años despues, terminaran superandola. Cuando seamos sobrepasados, en un primer momento, nos adaptaremos a esta supertecnologias, incorporandolas a nuestros organismos, expandiendo nuestras capacidades. Kurzweil intuye que nanobots incrustados en nuestros cerebros, musculos, arterias, etc., multiplicaran nuestras habilidades convirtiendonos en cyborgs superinteligentisimos. Tambien impediran que enfermemos y alargaran extensamente nuestras vidas. No obstante, algunos como el principe Carlos de Inglaterra, creen que las nanomaquinas al multiplicarse podrian destruir la Tierra. Pero Kurzweil asegura que nanocontrapartes, combatiran cualquier desajuste nanotecnológico, ademas de la contaminacion ambiental, virus y la pobreza, generando alimentos a voluntad. Sin embargo, la gran especializacion nanotecnologica, corre el riesgo de abrir un nuevo espacio, la terrorifica posibilidad de que las nanomaquinas se autorepliquen, adquieran conciencia propia y decidan prescindir de nosotros.
