[Question] What about transhumans and beyond?

When it comes to AGI alignment, or just the future in general, it seems many people think in a way that revolves all around humans as we know them today. Take the recent Kurzgesagt video “The Last Human – A Glimpse Into The Far Future” for instance. While it does very briefly mention the possibility of genetic engineering, it doesn’t go into detail and clearly considers the human descendants to still continue with rather similar properties as today’s humans, since it is calculating a number of hypothetical human births. If it would for example consider the possibility of human-like artificial minds, which could hypothetically be created more quickly and efficiently, that could dwarf the number of humans given the same resources.

So is this human purist view not rather myopic in the long run?

There of course also are humans that would eagerly accept deeply invasive modifications of their bodies, as long as those modifications appear sufficiently beneficial to them. Over time such biotechnological modifications could result in transhumans that barely resemble today’s humans, effectively creating a very different, even “alien”, lifeform.

Or what if some transhumans eventually wish to transfer or connect or recreate their minds in some kind of virtual world system, which may or may not also allow control of “bodies” in the outside world? Would you consider such a mind any less of a person because it can be easily copied, or because it is not restricted to a specific human body, or for some other reason?

The modifications could eventually go so far as to create transhumans on par with a possibly already existing aligned AGI.
Of course transhumans and human purists could ostensibly coexist even in extreme modification scenarios. But perhaps the human purists would try to forcefully prevent a greater extent of transhumanism out of fear, or perhaps the transhumans would fight the purists for resources, who knows.

What do you think?
