How tech harvests our humanity

The second in a three-part series exploring the implications of technology.

James is Canon Missioner at Blackburn Cathedral. He researches technology and theology at Oxford University.

In the first article, I painted a picture of the ordinary person using modern technology, for example, social media on a smart phone. I noted that advocates for modern technology seem to have two basic principles: that technology is natural and neutral. In this next article I want to introduce the philosophy of Martin Heidegger and show how he pushes against these two basic principles and invites us to think again about modern technology. Heidegger’s instinct, as a twentieth century philosopher, is to be suspicious that things are not as they seem, he casts his suspicious gaze over modern technology and sees a way of being that technology encourages that exists underneath the technologies that we use every day. 

What Heidegger wants to show us about modern technology is not related to specific concerns about particular technologies but instead a general suspicion about the ‘essence’ of technology, or, you could say, the spirit of technology. He doesn’t want us to immediately jump to pragmatic questions about how to use technology, as if the primary question is how to make any given technology better or more moral. Instead, Heidegger wants us to take modern technology together as a whole and ask, “What is the essence of this?” Heidegger’s contention is that “technology is not an object or set of objects, nor a way of handling objects with tools, but a form of being the world. It is not something we choose to refuse, but the environment in which modern humans come into existence.”

Heidegger argues that underneath any piece of tech that we might use in our day-to-day lives, technology at its core has already completely changed the way that we as a society understand and interact with the world and everything in it. We live in a technological age and as members of a technological society and so we have been shaped by (to use Christian language, we have been ‘discipled’ by) the spirit of the age to see the world around us. Heidegger suggests that we now see the world as broken down into useable bits that can be categorised and reformed to suit our needs. As Mark Wrathall puts it, the essence of technology is to train us to “experience the world as calling on us or drawing us. To transform everything into stock pieces, so that they can be placed into a vast inventory of options.”[2] Growing up in a technological society means that we see the whole world as an Amazon warehouse a place of seemingly limitless options that can be called upon depending on our needs and quickly delivered.  

A piece of technology such as the smartphone points to a wider ‘spirit’ of technology which intends to position everything, even human beings, as replaceable resources within a larger system. 

The central word that Heidegger uses to describe the essence of technology is gestell which is not an easy word to translate into English, but two possible translations would be ‘positionality’, or ‘enframing’. His point is that the essence of technology is to remove objects, people, and things from their natural environment and position them so that they might become useful, a resource, available for our manipulation. When Heidegger says that the essence of technology is gestell he is pointing to the way that modern technology extracts objects from their contexts and turns them into a quarry to the plundered. There are of course obvious ways in which humanity has always extracted resources from the natural world: we have always quarried for energy (coal, oil etc) or chopped down forests for wood. By claiming that the essence of modern technology is gestell, Heidegger wants us to notice that in the modern world, it’s not just quarries or forests that we mine for resources but now anything and everything can be turned from being a singular object in the world into a recourse for extraction. Everything has become what Heidegger calls “standing reserve.”  

Think again of a smartphone, it is just one of the billions of devices that sit on shelves or, having already been purchased, live in someone else’s pocket. Inside each device are thousands of transistors and circuit boards each of which again are stockpiled in warehouses ready to be replaced if needed or used for some other purpose. Your phone is connected to a network of nodes each of which can be replicated or replaced if needed, no node is unique.  Your latest phone has no unique or prize relation to you, it’s just the latest upgrade which will be recycled in a year or two when the next upgrade becomes available. The person from whom you bought the phone is equally replaceable, just a faceless employee completing a set of controlled and pre-arranged tasks that are designed to be completed by anyone and no one in particular. Likewise, you as the consumer are considered to be little more than “standing reserve” by the companies that supply you with your smartphone and access to their networks. One of many millions of nodes in their system that has been analysed so that your preferences can be expertly mapped to the range of services that they provide. Within that system, you are completely replaceable. A piece of technology such as the smartphone points to a wider ‘spirit’ of technology which intends to position everything, even human beings, as replaceable resources within a larger system: “Every item within this standing reserve is reduced to a position, actively waiting to be called on. Heidegger insists this is no judgment on the radio, the internet, or the smartphone user. It is just the way in which the essence of modern technology interacts with humanity… Heidegger provides a diagnosis of our modern age and the way in which we humans have placed ourselves under the sway of modern technology, as a resource standing within a network which seeks, ultimately, to place, represent, and think of every entity as an object within an all-encompassing system.”

Let’s return to the original thought experiment at the start of the first article: a mother playing with her child, who immediately reaches for her phone to capture the moment when her child does something particularly cute. An advocate for modern technology, like Steve Jobs, may look at that interaction and see only the benefit: a mother wanting to remember a beautiful moment with her child extends the capacities of her brain using a digital tool to aid her memory. But Heidegger would be more suspicious, he would look at that moment and argue instead that the essence of technology is to turn everything, even a precious moment with a cute baby, into a resource to be used at a later date. The unique moment of joy and delight between parent and child becomes caught and codified such that it can be found and replayed at will or easily replicated to send to others. At the extreme end of the spectrum are so-called content creators who reduce themselves to just another resource to be harvested on social media. 

So that is Heidegger’s diagnosis of our technological age, in the final article in this series we will consider Heidegger’s solution and consider what a particularly Christian response to Heidegger’s diagnosis might look like.

Ethics needs to catch-up with genetic innovation

Are we morally obliged to genetically edit?

It makes me feel very old when I realise that Louise Brown, the first baby to be born via in vitro fertilisation (IVF), will be 47 years old on July 25th this year. Since her birth in 1978, over 10 million IVF-conceived babies have been born worldwide, of whom about 400,000 have been in the UK. Over that period, success rates have increased such that in some clinics, about 50 per cent of IVF cycles lead to a live birth. At the same time, there have also been significant advances in genetics, genomics and stem cell biology all of which, in relation to human embryos, raise interesting and sometimes challenging ethical issues. 

I start with a question: what is the ‘moral status’ of the early human embryo? Whether the embryo arises by normal fertilisation after sexual intercourse or by IVF, there is a phase of a few days during which the embryo is undergoing the earliest stages of development but has not yet implanted into the wall of the uterus; the prospective mother is not yet pregnant. In UK law, based on the Human Fertilisation and Embryology Act (1990), these early embryos are not regarded as human persons but nevertheless should be treated with some respect. Nevertheless, there are some who oppose this view and believe that from the ‘moment of conception’ (there actually isn’t such a thing – fertilisation takes several hours) embryos should be treated as persons. In ‘conventional’ IVF this debate is especially relevant to the spare embryos that are generated during each IVF cycle and which are stored, deep-frozen, in increasing numbers for possible use in the future.  

A further dimension was added to this area of debate when it became possible to test IVF embryos for the presence of genetic mutations that cause disease. This process is called pre-implantation genetic diagnosis and enables prospective parents who are at known risk of passing on a deleterious mutation to avoid having a child who possesses that mutation. But what about the embryos that are rejected? They are usually discarded or destroyed but some are used in research. However, those who hold a very conservative view of the status of the early embryo will ask what right we have to discard/destroy an embryo because it has the ‘wrong genes’. And even for the many who hold a less conservative view, there are still several questions which remain, including ‘which genetic variants we should be allowed to select against?; should we allow positive selection for genes known to promote health in some way?’; should we allow selection for non-therapeutic reasons, for example, sporting prowess?’ These questions will not go away and there are already indications that non-therapeutic selection is being offered in a small number of countries. 

Genetic modification 

This leads us on to think about altering human genes. Initially, the issue was genetic modification (GM) which in general involves adding genes. GM techniques have been used very successfully in curing several conditions, including congenital severe immune deficiency and as part of treatment programmes for certain very difficult childhood cancers. One key feature of these examples is that the genetic change is not passed on to the next generation – it just involves the body of someone who has already been born. Thus, we call them somatic genetic changes (from the Greek, sōmatikos, meaning ‘of the body’).  

Genetic modification which is passed on to the next generation is called germline GM which means that the genetic change must get into the ‘germ cells’, i.e., the sperm or egg. Currently, the only feasible way of doing this is to carry out the genetic modification on the very early embryo. At present however, with just one very specific exception, GM of human embryos is forbidden in all the countries where it would be possible to do it. There is firstly the question of deciding whether it is right to change the genetic makeup of a future human being in such a way that the change is passed to succeeding generations. Secondly, there are concerns about the long-term safety of the procedure. Although it would involve adding specific genes with known effects, the complexity of genetic regulation and gene interactions during human development means that scientist are concerned about the risks of unforeseen effects. And thirdly, germline GM emphasises dramatically the possibility of using GM for enhancement rather than for medical reasons.  

Genome editing 

This leads us to think about genome editing. In 2011, it was shown that a bacterial system which edits the genomes of invading viruses could also work in other organisms This opened up a large array of applications in research, agriculture and medicine. However, the ethical issues raised by genome editing are, in essence, the same as raised by GM and so there is still a universal prohibition of using the technique with human embryos: germline genome editing is forbidden. Despite this, a Chinese medical scientist, He Jiankui, announced in 2018 that he had edited the genomes of several embryos, making them resistant to HIV; two babies with edited genomes had already been born while several more were on the way. The announcement caused outrage across the world, including in China itself. He Jiankui was removed from his job and then, after a trial, was imprisoned for three years; his two colleagues who collaborated in this work received shorter sentences. 

At present the universal prohibition of human germline genome editing remains in place. However, the discussion has been re-opened in a paper by an Anglo-Australian group.  They suggest that we need to develop heritable (i.e. germline) polygenic genome editing in order to reduce significantly an individual's risk of developing degenerative diseases. These includecoronary artery disease, Alzheimer’s disease, major depressive disorder, diabetes and schizophrenia. I note in passing that one of the authors is Julian Savulescu at Oxford who is already well-known for his view that parents who are able to do so, are ‘morally obliged’ to seek to have genetically enhanced children, whether by PGD, GM or genome editing. The use of polygenic editing, which would, in all likelihood, be available only to the (wealthy) few, fits in well with his overall ethical position. Needless to say, the paper, published in the prestigious journal Nature, attracted a lot of attention in the world of medical genetics. It was not however, universally welcomed – far from it. Another international group of medical scientists and ethicists has stated that ‘Human embryo editing against disease is unsafe and unproven …’ and even go as far as to suggest that the technology is ‘… going to be taken up by people who are pushing a eugenics agenda …’ remain very pertinent. 

Harder still and harder 

I have no doubt that amongst different reader there will be a range of opinions about the topics discussed so far. For anyone who is Christian (or indeed an adherent of almost any religious faith), one of the difficulties is that modern science, technology and medicine have thrown up ethical questions that could not have even been dreamed of by the writers of the Bible (or of other religious texts). We just have to use our wisdom, knowledge and general moral compass (and for some, prayer) to try to reach a decision. And if what I have already written makes that difficult, some recent developments multiply that difficulty still more.  

In the early years of this century, scientists developed methods of transforming a range of human cells into ‘pluripotent’ stem cells, i.e., cells capable of growing into a wide range of cell types. It also became possible to get both induced stem cells and natural stem cells to develop into functional differentiated cells corresponding to specific body tissues. This has huge potential for repairing damaged organs. However, other applications are potentially much more controversial. In 2023, Cambridge scientists reported that they had used stem cells to create synthetic mouse embryos which progressed at least as far as brain and heart formation within the normal pattern of mouse embryo development. 

At about the same time, the Cambridge group used individual human embryonic stem cells (from the blastocyst stage of embryonic development), to ‘grow’ early human embryos in the lab. There is no intention to use these embryos to start a pregnancy – indeed, it would be illegal to do so – but instead to study a period of embryo development which is not permitted with ‘real’ human embryos (research must not continue past 14 days of development). But how should we regard synthetic embryos? What is their moral status? For those who hold a conservative view of the normal human embryo (see earlier), should we regard these synthetic embryos as persons? Neither does the law help us. The legal frameworks covering in vitro fertilisation and early embryos (Human Fertilisation and Embryology Acts, 1990, 2008) do not cover artificial embryos – they were unknown at the times the legislation was drawn up. Indeed, synthetic embryos/embryo models are, in law, not actually embryos, however much they look like/behave like early embryos. Earlier this month, the Human Fertilisation and Embryology Authority (HFEA) discussed these developments with a view to recommending new legislation, but this will not dispel an unease felt by some people, including the science correspondent of The Daily Telegraph, who wrote that this research is irresponsible.  

But there is more. In addition to synthetic embryos, the HFEA also discussed, the possible use of gametes – eggs and sperm – grown from somatic stem cells (e.g., from skin) in the lab. Some authors have suggested that the production of gametes in vitro is the ‘Holy Grail’ of fertility research. I am not so sure about that but it is clear that a lot of effort is going into this research. Success so far is limited to the birth of several baby mice, ‘conceived’ via lab-grown eggs and normal sperm. Nevertheless, it is predicted that lab-grown human eggs and sperm will be available within a decade. Indeed, several clinicians have suggested that these ‘IVGs’ (in vitro gametes) seem destined to become “a routine part of clinical practice”.  

The lab-grown gametes would be used in otherwise normal IVF procedures, the only novelty being the ‘history’ of the eggs and/or sperm. Clinicians have suggested that this could help couples in which one or both were unable to produce the relevant gamete, but who still wanted to have children. In this application, the use of IVGs poses no new ethical questions although we may be concerned about the possibility of the gametes carrying new genetic mutations. However, some of the more wide-ranging scenarios do at the least make us to stop and think. For example, it would be possible for a same-sex couple to have a child with both of them being a genetic parent (obviously for males, this would also involve a surrogate mother). More extremely, a person could have a child of which he or she was actually, in strictly genetic terms, both the ‘father’ and the ‘mother’. What are we to make of this? Where are our limits?  

Dr Christopher Wild, former director of International Agency for Research on Cancer, explores in depth many of the developments and issue I outlined above. His article on why a theology of embryos is needed, is clear, well-written, helpful and thought-provoking.
