As much as I celebrate advances in science and technology, I don’t deny there are instances where some advances it leads to unintended consequences. I’m sure the inventor of ski masks knows that all too well. In many cases, these missteps and mishaps are part of the ongoing challenge to use these advances responsibly. It’s akin to a maturation process that is often difficult, but still necessary.

In some cases, however, certain advances bring out some of humanity’s ugliest traits. Whether it’s a tool or an insight into the natural world, certain people who may or may not be malicious will use science to further a nefarious agenda. Of all the sciences that brought out the worst in humanity, eugenics is probably the most well-known.

The concept, itself, is not entirely abhorrent. If you look up the definition, this is what comes up.

The practice or advocacy of controlled selective breeding of human populations to improve the population’s genetic composition.

On paper, that has some objective merit. The world is a chaotic, dangerous place that’s constantly changing. In some cases, humanity is causing that change. If we’re to survive on a planet in which 99 percent of the species that have ever lived have gone extinct, it makes sense to improve our collective genetics so that we’re best equipped to survive.

Unfortunately, the details surrounding eugenics were permanently tainted when it became the preferred excuse for atrocities by the Nazis. Even before that, it was a popular talking point among racists seeking to marginalize or outright exterminate the impact of certain minorities within a society. At one point, there were organizations dedicated to promoting eugenics through forced sterilization and miscegenation laws.

The legacy of eugenics is so ugly that it’s almost synonymous with some of the worst acts of bigotry ever committed. When people think of eugenics, they don’t think of advancing human biology to make it more robust. They imagine racist tyrants forcibly sterilizing undesirable minorities in the hopes that they eventually die out in a silent genocide.

There’s no question that this form of eugenics is abhorrent. The way it was practiced throughout the 20th century was a perversion of science and technology. We would be wise to remember that as we make bigger and bolder advancements in science, especially for those related to biotechnology.

It’s here where the ugly legacy of eugenics seems destined to clash with science once more. In late 2018, news broke of a groundbreaking advance in biotechnology when a scientist named He Jiankui announced that the first genetically modified humans had been born. I went out of my way to note why this is a huge deal in the history of our species, but it’s also sparking distressing concerns related to eugenics.

Thanks to gene-editing tools like CRISPR, it’s now possible to edit the human genome with the same ease as copying and pasting text from a website. That has sparked concerns that it will be used to purge certain undesirables from the human population, just as was attempted with eugenics.

Logistically, there’s no reason why tools like CRISPR couldn’t be used to edit the genome of every child before they’re born to ensure they look a certain way. Granted, it would require some fairly invasive policies, but that has never stopped ambitious governments in the past. As these tools are refined, it’ll only get easier to pursue the kinds of racist policies that deplorable bigots in the past once favored.

However, this is not a fair association, nor is it constructive in addressing the legitimate issues surrounding the use of CRISPR and so-called designer babies. Linking this technology to eugenics is akin to blaming every nuclear physicist for the destruction of Hiroshima and Nagasaki. It’s not just because the potential of this technology is so great. The intent behind it differs considerably with that of eugenics.

That intent shows in the specifics of the first two genetically modified children. These children were not born out of a desire for racial superiority. The modifications made to their genome was intended to make them more resistant to HIV/AIDS infection. That’s an objective good. Healthier babies who are more resistant to disease is a benefit to our species, as a whole.

In addition, this feat was achieved without sterilizing someone against their will or without the consent of the parents. While there were some legitimate ethical concerns, the underlying purpose has little to do with furthering racial goals and more to do with combating disease and suffering. This is where the difference between eugenics and designer babies at its most stark.

Eugenics, historically speaking, was almost always pursued with a racial agenda. It never stopped at just treating disease. Its advocates sought more than just health. They sought superiority. That’s not how the emerging technology surrounding CRISPR is being used. It’s following a similar path to that of in-vitro fertilization, which was subject to plenty of controversy as well.

Like any technology, there are going to be legitimate concerns mixed in with the doomsayers. With CRISPR and designer babies, the concerns will be greater because the stakes will be higher. We’re not just talking about a technology that will reduce the risk of inherited diseases. This technology could fundamentally change the human race in a very literal sense.

Designer babies, much like their in vitro counterparts, will be part of that change. Regardless of how someone feels about endowing a baby with the genetics of Tom Brady and Stephen Hawking, the potential for good is just too vast. Thousands of people die every year because of diseases that are written into their genes. This technology, if properly refined, could render such suffering a distant memory.

Hesitating with this technology because of potential links to eugenics will only prolong this suffering. In the same way countless individuals wouldn’t be alive without in-vitro fertilization, there are countless people who aren’t alive now because this technology wasn’t available to help them.

Treating diseases and ensuring the health of the next generation is a common good that eugenics corrupted with racist ideology. It attempted to do that by using science and technology to more effectively oppress their chosen enemies. That is radically different than editing the genes of a child so they don’t succumb to certain diseases.

That’s not to say there aren’t risks. At some point, someone will try to abuse this technology and it’s likely that person will have unpopular views on eugenics. There will also be a point where this technology isn’t just used to treat diseases. It will also be used to implement traits and abilities within people that aren’t possible by natural means.

The merits and ethics of such genetic tampering are definitely worth discussing, but references to eugenics will only serve to derail that discussion for all the wrong reasons. Like it or not, humans will need to keep adapting and growing in our chaotic world. If we ever hope to outlast our planet and even our sun, we can’t be bound by genetic constraints or outdated attitudes.

That makes developing genetics technology all the more vital. Eugenics was a bad ideology that hijacked a lot of good science. Whatever your opinion may be on designer babies and improving the human genome, the technology is here. Children born of this technology have arrived. The benefits are vast, provided we have the right approach.
