Technology always advances faster than ethics. Leaving society and individuals floundering in it wake. The printing press transformed European society in the sixteenth century. The cotton gin transformed the economy of the US South, arguably deepening Slavery, and instituting a pattern of violence and cultural wars which have lasted to this day. In the last century, the development of nuclear fission and computing have effected changes as profound as any known in History. It is with these examples in mind that we approach the subject of Human Genome Editing, which may make everything before look silly.
This has been a decade in which the effective manipulation of nucleic acids in living systems has become routine. We have covered such exciting techniques as CRISPR Cas-9 and Base Pair Editing. While all educated people stand in awe of the rapid advance of mRNA vaccine technology, which did so much to stem the COVID-19 pandemic and now offers real hope of new cancer treatments. But, without disparaging the intellectual brilliance or immense hard work of their creators, these technologies are relatively small scale in the size of the biological interventions which they entail. So now read this from Nature Briefings:
Brace for the arrival of Gene editing Modifying multiple DNA variants in human embryos at the same time, a process called polygenic genome editing, could substantially reduce the likelihood of certain diseases occurring. But it also raises concerns, say the authors of a Nature analysis — not least the renewed threat of eugenics. “This is not a hypothetical issue,” argues an accompanying Nature editorial. While such genome editing might be decades off, societies need to consider its possible benefits and risks now to avoid having to play regulatory catch-up when the technology becomes available.Nature | 4 min read

Imagine a society where the very richest may edit the DNA of themselves and their offspring so that they, and they alone form a race of superbeings. The future for the rest of human kind, the untermenschen if you will, looks grim, and may be very brief. Such evolutionary bottlenecks have occurred in the past; and those on the wrong side(always the majority) “fly forgotten as a dream, flies at the end of day” as the old hymn puts it. Time to consider this very seriously indeed we think. Nature thinks you may have 30 years: we suspect it to be much shorter than that.
