What is Artificial Intelligence?

AI and Machine Learning

Artificial Intelligence (AI): computer systems that can perform tasks normally requiring human intelligence — e.g. recognising images, translating language, playing chess, driving cars.

Machine Learning (ML): a type of AI where systems learn from data rather than being explicitly programmed. Given training data, they identify patterns and improve over time.

Deep learning: a subset of ML using neural networks with many layers — enables image and speech recognition

Examples: spam filters, recommendation engines (Netflix, YouTube), voice assistants (Siri, Alexa)

Robotics & Automation

Machines Doing Human Jobs

Industrial robots: car manufacturing, welding, assembly — precise, tireless, and consistent

Autonomous vehicles: self-driving cars use sensors, cameras, and AI to navigate without human input

Surgical robots: AI-assisted surgery (e.g. da Vinci) allows more precise operations with smaller incisions

Warehouse robots: Amazon and similar companies use robots for picking, packing, and sorting

Ethical Issues with AI

Benefits and Concerns

Job displacement: automation threatens jobs in manufacturing, transport, retail, and even some professional roles. New jobs are created, but may require different skills — causing displacement.

Bias: AI trained on biased data can produce unfair outcomes — e.g. facial recognition performing worse on darker skin tones

Accountability: when an AI makes a mistake, who is responsible — the programmer, the company, the user?

Benefits: improved healthcare diagnosis, personalised education, faster drug discovery

Edexcel-style question

Describe one social benefit and one ethical concern of increasing use of AI in healthcare.

4 marks

Benefit: AI can analyse medical images faster and more accurately than humans [1], allowing earlier diagnosis of conditions such as cancer and improving patient outcomes [1]. Ethical concern: if an AI misdiagnoses a patient, it is unclear who is legally responsible [1] — the developer, hospital, or AI system — which raises accountability issues [1].

Key Takeaways

What to Remember

AI: simulates human intelligence; ML: learns from data without explicit programming

Robotics automate manufacturing, surgery, transport, logistics

Concerns: job displacement, algorithmic bias, accountability, privacy

Benefits: healthcare, efficiency, safety — but must be weighed against ethical risks
