Artificial intelligence could soon be used to perform radiotherapy to treat certain cancers for the first time. Draft guidance from the National Institute for Health and Care Excellence (Nice) has given approval to nine AI technologies for performing external beam radiotherapy in lung, prostate and colorectal cancers, which could save radiographers hundreds of thousands of hours and help relieve pressure on radiotherapy departments. Currently therapeutic radiographers outline healthy organs on digital images of a CT or MRI scan by hand so that the radiotherapy does not damage healthy cells by minimising the dose to normal tissue. Nice found that using AI to create the contours could free up between three and 80 minutes of radiographers’ time for each treatment plan, and that AI-generated contours were of a similar quality to manually drawn ones. Nice said that the contours would still be reviewed by a trained healthcare professional. It comes after a study found AI was safe to use in breast cancer screenings with evidence growing that it can be more effective in detecting cancers.

Dr Sarah Byron, the programme director for health technologies at Nice, said using AI could help reduce waiting lists. She added: “NHS colleagues working on the frontline in radiotherapy departments are under severe pressure with thousands of people waiting for scans. “The role imaging plays in radiotherapy treatment planning is quite pivotal, so recommending the use of AI technologies to help support treatment planning alongside clinical oversight by a trained healthcare professional could save both time and money. “We will continue to focus on what matters most and the recommendations made by our independent committee can help to bring waiting lists down for those needing radiotherapy treatment.” The health secretary, Steve Barclay, welcomed the announcement. He said: “It’s hugely encouraging to see the first positive recommendation for AI technologies from a Nice committee, as I’ve been clear the NHS must embrace innovation to keep fit for the future. “These tools have the potential to improve efficiency and save clinicians thousands of hours of time that can be spent on patient care. Smart use of tech is a key part of our NHS long-term workforce plan, and we’re establishing an expert group to work through what skills and training NHS staff may need to make best use of AI.” Charlotte Beardmore, the executive director of professional policy at the Society of Radiographers, welcomed the draft guidance but said it was not a replacement for staff and caution was needed. “It is critical there is evidence to underpin the safe application of AI in this clinical setting,” she said. Using AI would still require input by a therapeutic radiographer or another member of the oncology multi-professional team, she added. “Investment in the growth of the radiography workforce remains critical.” Science is pretty amazing.

This highly anticipated podcast of Adin Ross is scheduled to take place on July 16

They are 22 words that could terrify those who read them, as brutal in their simplicity as they are general in their meaning: “Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war.” That is the statement from San Francisco-based non-profit the Center for AI Safety, and signed by chief executives from Google Deepmind and ChatGPT creators OpenAI, along with other major figures in artificial intelligence research. The fact that the statement has been signed by so many leading AI researchers and companies means that it should be heeded. But it also means that it should be robustly examined: why are they saying this, and why now? The answer might take some of the terror away (though not all of it). Writing a statement like this functions as something like a reverse marketing campaign: our products are so powerful and so new, it says, that they could wipe out the world. Most tech products just promise to change our lives; these ones could end it. And so what looks like a statement about danger is also one that highlights just how much Google, OpenAI and more think they have to offer. Warning that AI could be as terrible as pandemics also has the peculiar effect of making artificial intelligence's dangers seem as if they just arise naturally in the world, like the mutation of a virus. But every dangerous AI is the product of intentional choices by its developers – and in most cases, from the companies that have signed the new statement. Who is the statement for? Who are these companies talking to? After all, they are the ones who are creating the products that might extinguish life on Earth. It reads a little like being hectored by a burglar about your house’s locks not being good enough. None of this is to say that the warning is untrue, or shouldn't be heeded; the danger is very real indeed. But it does mean that we should ask a few more questions of those warning us about it, especially when they are conveniently the companies that created this ostensibly apocalyptic tech in the first place. AI doesn't feel so world-destroying yet. The statement's doomy words might come as some surprise to those who have used the more accessible AI systems, such as ChatGPT. Conversations with that chatbot and others can be funny, surprising, delightful and sometimes scary – but it's hard to see how what is mostly prattle and babble from a smart but stupid chatbot could destroy the world. They also might come as a surprise to those who have read about the many, very important ways that AI is already being used to help save us, not kill us. Only last week, scientists announced that they had used artificial intelligence to find new antibiotics that could kill off superbugs, and that is just the beginning. By focusing on the "risk of extinction" and the "societal-scale risk" posed by AI, however, its proponents are able to shift the focus away from both the weaknesses of actually existing AI and the ethical questions that surround it. The intensity of the statement, the reference to nuclear war and pandemics, make it feel like we are at a point equivalent with cowering in our bomb shelters or in lockdown. They say there are no atheists in foxholes; we might also say there are no ethicists in fallout shelters. If AI is akin to nuclear war, though, we are closer to the formation of the Manhattan Project than we are to the Cold War. We don’t need to be hunkering down as if the danger is here and there is nothing we can do about it but “mitigate it”. There's still time to decide what this technology looks like, how powerful it is and who will be at the sharp end of that power. Statements like this are a reflection of the fact that the systems we have today are a long way from those that we might have tomorrow: the work going on at the companies who warned us about these issues is vast, and could be much more transformative than chatting with a robot. It is all happening in secret, and shrouded in both mystery and marketing buzz, but what we can discern is that we might only be a few years away from systems that are both more powerful and more sinister. Already, the world is struggling to differentiate between fake images and real ones; soon, developments in AI could make it very difficult to find the difference between fake people and real ones. At least according to some in the industry, AI is set to develop at such a pace that it might only be a few years before those warnings are less abstractly worrying and more concretely terrifying. The statement is correct in identifying those risks, and urging work to avoid them. But it is more than a little helpful to the companies that signed it in making those risks seem inevitable and naturally occurring, as if they are not choosing to build and profit from the technology they are so worried about. It is those companies, not artificial intelligence, that have the power to decide what that future looks like – and whether it will include our "extinction".
