In a new post, Nostalgebraist argues that "AI doomerism has its roots in anti-deathist transhumanism", representing a break from the normal human expectation of mortality and generational change.
They argue that traditionally, each generation has accepted that they will die but that the human race as a whole will continue evolving in ways they cannot fully imagine or control.
Nostalgebraist argues that the "anti-deathist" view, however, anticipates a future where "we are all gonna die" is no longer true -- a future where the current generation doesn't have to die or cede control of the future to their descendants.
Nostalgebraist sees this desire to "strangle posterity" and "freeze time in place" by making one's own generation immortal as contrary to human values, which have always involved an ongoing process of change and progress from generation to generation.
This argument reminds me of Elon Musk's common refrain on the topic: "The problem is when people get old, they don't change their minds, they just die. So, if you want to have progress in society, you got to make sure that, you know, people need to die, because they get old, they don't change their mind." Musk's argument is certainly different and I don't want to equate the two.
I'm just bringing this up because I wouldn't bother responding to Nostalgebraist unless this was a common type of argument.
In this post, I'm going to dig into Nostalgebraist's anti-anti-deathism argument a little bit more. I believe it is simply empirically mistaken. Key inaccuracies include:
1: The idea that people in past "generations" universally expected to die is wrong. Nope. Belief in life after death or even physical immortality has been common across many cultures and time periods.
Quantitatively, large percentages of the world today believe in life after death:
In many regions, this belief was also much more common in the past, when religiosity was higher. Ancient Egypt, historical Christendom, etc.
2: The notion that future humans would be so radically different from us that replacing humans with any form of AIs would be equivalent is ridiculous.
This is just not close to my experience when I read historical texts. Many authors seem to have extremely relatable views and perspectives.
To take the topical example of anti-deathism, among secular authors, read, for example, Francis Bacon, Benjamin Franklin, or John Hunter.
I am very skeptical that everyone from the past would feel so inalienably out of place in our society today, once they had time (and they would have plenty of time) to get acquainted with new norms and technologies. We still have basically the same DNA, gametes, and in utero environments.
3: It is not the case that death is required for cultural evolution. People change their minds all the time. Cultural evolution happens all the time within people's lifespans. Cf: views on gay marriage, the civil rights movement, environmentalism, climate change mitigation, etc.
This is especially the case because in the future we will likely develop treatments for the decline in neuroplasticity that can (but does not necessarily always) occur in a subset of older people.
Adjusting for (a) the statistical decline of neuroplasticity in aging and (b) contingent aspects of the structure of our societies (which are very much up for change, e.g. the traditional education/career timeline), one might even call death and cultural evolution "orthogonal".
4: No, our children are not AIs. Our children are human beings.
Every generation dies, and bequeaths the world to posterity. To its children, biological or otherwise. To its students, its protégés. ...
