The history of AI is often presented as a march toward the inevitable. It is better understood as a series of choices: what to measure, what to fund, whose data to collect, and who bears the cost when systems fail. In the season finale, we revisit the recurring cycle of bold claims, remarkable demonstrations, practical limits, and reinvention. Then we look beyond algorithms to the infrastructure and institutions beneath them—chips, data centres, workers, electricity, companies, and governments. History cannot predict AI’s future, but it can remind us that the future is still open to argument.

For most people, AI was once hidden inside recommendation engines, laboratories, and specialist tools. Then a blank chat box invited anyone to ask a question. We trace the path from language models to instruction-following and reinforcement learning from human feedback, explaining why helpfulness and fluency are engineered behaviours rather than evidence of personhood. The conversational interface opened remarkable uses in writing, translation, accessibility, coding, and tutoring. It also made hallucinations, bias, copyright disputes, and labour questions impossible to ignore. When a machine becomes persuasive, literacy becomes essential.

To understand a sentence, a reader constantly decides which words matter to one another. The transformer turned a version of that relationship into a scalable mathematical mechanism called attention. Beginning with the 2017 paper “Attention Is All You Need,” this episode explains why transformers changed language modelling, why parallel processing mattered, and how scale became a research strategy. More data, compute, and parameters produced increasingly fluent systems—and an increasingly important warning: language that sounds meaningful can still be wrong. Fluency is an achievement, not proof of understanding.
