I think that is framing survival too far into the abstract to be of any concrete use, which in turn negates the abstract.
This doesn't make sense. I appreciate you trying to employ the jargon, but something being impractical doesn't negate its structural logic in thought.
This concept of survival finds paradox in its very logic. Most practical behavior is illogical and/or irrational. The point here isn't behavior, but the logic of life and survival. "Survival," as it currently stands, is an enigmatic and ideological construct, however much we like to think of it as a physico-biological given.
Ultimately, for the homoeconomicus or whatever, it is an evolutionary hardwiring of the biomass that directs it to take action that ensures genetic propagation.
This is a grievous misunderstanding that I actually feel is the most important part of your post, and I think we should rectify it.
Evolution and "survival" don't ensure genetic propagation; evolution isn't directed in this sense. Organisms have no choice over their evolutionary adaptations, and genetics have no intentions in their mutations. Saying that genes mutate in order to ensure survival projects an intention and a design that is not really there.
Rather, evolutionary survival happens by sheer chance; those organisms whose adaptations allow them to weather the elements will survive, and pass on their genes to the next generation: survival of the luckiest.
We have, of course, never escaped the age of bacteria; and we never will. The human isn't some more effective form of life that bacteria strove toward in order to ensure their survival in the form of parasites of our intestinal systems. Bacteria would exist without us, some way or another; and bacteria are the supreme example of organisms whose existence depends monumentally on their constant integration into other living systems.
What that is and requires may evolve. Land, and moldbuggian positions as I understand them, interpret survival in this way. Technology is just seen as another flow of "genetic" propagation from a Landian accelerationist point of view, and a more rigid (or maybe fluid?) view of the singularity envisions a mixing of the two genetic flows.
Advantageous adaptations don't simply arrive to those who need them, or prove disadvantageous to those who fail to use them properly. There is no directive to evolutionary development. Evolution has no foresight. Survival cannot be the directed pulse of life toward advantageous mutation which it then employs rigorously against an outside world of external stimuli; this is simply an inaccurate view of the world.
At the root of all thriving organisms, survival doesn't exist. Survival is something we project onto the world.
Of course, to NRx, the Cathedral is a threat to Survival.
I don't think Land even has a clear idea of what the Cathedral is.
