A Brief History Of AI
AI did not begin with modern computers. Alan Turing’s 1950 paper Computing Machinery and Intelligence laid the foundation for machines that could mimic human reasoning. Early programmes in the 1950s and 1960s played noughts‑and‑crosses or generated love letters, demonstrating basic computational “intelligence”.
By the 1970s and 1980s, thinkers like Margaret Boden and Andy Clark shifted the goal from building machines that think to machines that perform tasks humans would consider intelligent. This reframing shaped decades of research.
AI surged again in the 1980s when John Hopfield and David Rumelhart popularised deep‑learning techniques. Expert systems emerged, capturing specialists' knowledge and providing answers to non‑experts. Countries such as Japan and the USA invested heavily.
Progress stalled until the 1990s, when IBM’s Deep Blue defeated world chess champion Garry Kasparov. Dragon Systems’ speech recognition software entered Windows, and Kismet introduced emotional recognition in robotics, challenging the Turing Test.
The internet ushered in the age of big data. Between 2011 and 2020, AI milestones included Siri, neural networks for traffic sign recognition, generative adversarial networks, facial recognition systems and self‑driving car trials. In 2018, OpenAI released GPT, paving the way for today’s large language models.
Why ChatGPT Matters For Healthcare
After 70 years of innovation, why has ChatGPT captured global attention?
The NHS is facing unprecedented strain. More than 7.4 million people are waiting for treatment. The service is projected to overspend its 2024 budget by at least £7bn. Bureaucracy, mismanagement and patient dissatisfaction have created a system in urgent need of reinvention.
AI could be the NHS’ most realistic lifeline. Previous attempts, such as Babylon Health’s digital‑first GP service, fell short. But the versatility of modern LLMs makes renewed exploration worthwhile.
Google’s MedLM, designed specifically for healthcare, aims to support clinicians with tasks such as hands‑free medical note‑taking through platforms like Augmedix. Tools like these could reduce administrative burdens, improve accuracy and free clinicians to focus on patient care.
The biggest obstacle is not the technology. It is regulation.
Regulation: Protection Or Prevention?
The EU’s politically agreed AI Act introduces strict controls on high‑risk AI systems. It prohibits practices such as biometric categorisation, real‑time facial recognition and cognitive behavioural manipulation. These safeguards protect privacy and prevent misuse.
However, mandatory pre‑market assessments for certain AI systems could slow innovation. Companies in EU member states may struggle to compete globally if their products take longer to reach consumers.
The UK, no longer bound by EU law, is not required to adopt the Act. But international pressure could influence its direction. The government plans to publish tests that must be satisfied before passing new AI laws. These tests would act as a safety net if the UK’s AI Safety Institute fails to identify risks. According to the Financial Times, the government wants evidence that regulation would mitigate risks without stifling innovation.
The UK must decide whether to prioritise protection or progress.
What Should We Take From This?
AI has evolved from simple rule‑based programmes to models capable of writing, analysing and creating with near‑human fluency. This rapid acceleration has sparked both excitement and fear.
The EU AI Act is a necessary starting point for global conversations about AI’s future. Whether its restrictions are too heavy‑handed remains to be seen. The challenge is that we do not yet know what we are protecting against. A far more advanced model may overshadow today’s ChatGPT within two years.
Given this uncertainty, regulators are understandably cautious. But for sectors like healthcare, where innovation could save lives, the UK must strike a careful balance between safety and progress.
