How can a random process produce the code, the understanding of the code and a system that corrects itself? Again, natural selection doesn't have anything to do with it until the gene reaches the environment.
Genetics deals with the molecular structure and function of genes, with gene behavior in the context of a cell or organism (e.g. dominance and epigenetics), with patterns of inheritance from parent to offspring, and with gene distribution, variation and change in populations. Given that genes are universal to living organisms, genetics can be applied to the study of all living systems, from viruses and bacteria, through plants (especially crops) and domestic animals, to humans (as in medical genetics). The fact that living things inherit traits from their parents has been used since prehistoric times to improve crop plants and animals through selective breeding. However, the modern science of genetics, which seeks to understand the process of inheritance, only began with the work of Gregor Mendel in the mid-19th century.[6] Although he did not know the physical basis for heredity, Mendel observed that organisms inherit traits via discrete units of inheritance, which are now called genes.
Although genes contain all the information an organism uses to function, the environment plays an important role in determining the ultimate phenotype—a phenomenon often referred to as "nature vs. nurture". The phenotype of an organism depends on the interaction of genetics with the environment.

Where is the intelligence in 99% of all species going extinct? That's the opposite of intelligence!
1; In "The Origin of Life" by Paul Davies (2003) the author notes that 99% of all species have gone extinct - around 3 973 000 000 species have died out completely
2. The number of species that have become extinct is from ten to a hundred times those which exist today
3 - and that's not including the present "sixth mass extinction" which is caused by humankind's mass destruction of natural habitats. The vast majority of biologists and zoologists know that life is not 'designed' at all - let alone in an intelligent manner.
Not only is this a painful process for the mother, but the human baby is probably one of the least developed of all mammals at birth, in fact you could say it's so helpless that relative to other mammals it's almost like a fetus that continues to develop outside the womb. If evolution was going to design human birth intelligently, it would have done a much better job than it did.
Our birthing mechanism works best if our hips were still orientated for all-fours walking. As Humankind has continued to evolve, brain size has got bigger and bigger, meaning that now Human babies have to be born underdeveloped so that their brain can continue to grow and mature outside the womb, after birth at an awkward angle through the too-narrow birth canal. Giving birth through the pelvis has turned out to be severely limiting giving our new posture and increasing skull size; now, agility (defined by narrow hips) and baby brain-size are in direct competition. What a mess! If only evolution operated with some foresight, things would have turned out somewhat more practically....
It would be silly to say that these cells are not computers but it seems to be irrelevant to the topic of the thread:

Cell combines a general-purpose Power Architecture core of modest performance with streamlined coprocessing elements[2] which greatly accelerate multimedia and vector processing applications, as well as many other forms of dedicated computation.
...not computers...not programmable...
Scientists have successfully demonstrated that they can build some of the basic components for digital devices out of bacteria and DNA, which could pave the way for a new generation of biological computing devices, in research published today in the journal Nature Communications.
elf-replication has also been implemented with synthetic systems, including RNA enzymes designed to undergo self-sustained exponential amplification1, 2, 3, 4, 5. An exciting next step would be to use self-replication in materials fabrication, which requires robust and general systems capable of copying and amplifying functional materials or structures. Here we report a first development in this direction, using DNA tile motifs that can recognize and bind complementary tiles in a pre-programmed fashion.
Mimicking cells with transistors Analog — rather than digital — circuits could enable models of biological systems that are more efficient, more accurate and easier to build.
PASADENA, Calif.—In many ways, life is like a computer. An organism's genome is the software that tells the cellular and molecular machinery—the hardware—what to do. But instead of electronic circuitry, life relies on biochemical circuitry—complex networks of reactions and pathways that enable organisms to function. Now, researchers at the California Institute of Technology (Caltech) have built the most complex biochemical circuit ever created from scratch, made with DNA-based devices in a test tube that are analogous to the electronic transistors on a computer chip.

..."cells = computers = intelligently designed"...
All of the above is hijacking nature to do man's dirty work.
this is not simply a matter of man's extraction of combustible materials from the earth in order to power our motors (which is what i think more accurately descibes "hijacking nature"). rather, there is a technology built into the system. this is categorically differernt, i think.

fine. you win. i restate it thus:
cells are biocomputers.
there. the semantics argument is over. for a definition of "biocomputer", please see above. and please do not next tell me that i am not free to coin my own terms or that such terms are meaningless.
YES. YOU ARE BEING OBTUSE.
That video and the link is extremely relevant to your OP and the point you just made.

Everything you said in your post and the stuff in the video you posted has nothing to do with anything I said in my OP..You're talking about how life behaves after the fact or after the fit gene has reached the environment. ...
The gene is fit before it reaches the environment and whether or not it survives is a random process so of course there will be a lot of extinctions because some of these traits don't survive in the environment.
What you are doing is taking standard words that have meanings defined in the dictionary, and using those words in a manner other than they are commonly defined.
