What AI Can and Can't Do Today

For people

A realistic view of current AI capabilities and limits, to help separate genuine opportunities from hype.

AI capability has advanced quickly, but it is uneven. A clear view of strengths and weaknesses helps you pick sensible projects.

Where AI Performs Well

  • Perception: recognising objects in images, transcribing speech, reading documents.
  • Language: drafting, summarising, translating, classifying and extracting information from text.
  • Pattern-finding at scale: fraud detection, recommendations, demand forecasting.
  • Code: generating, explaining and reviewing routine code.
  • Narrow, well-defined tasks with plenty of representative data.

Where It Struggles

  • Reliability on specifics: exact figures, citations and rare facts can be invented.
  • Novel situations: performance drops when inputs differ from training data.
  • Long chains of reasoning without feedback or verification.
  • Common sense and physical understanding in unfamiliar settings.
  • Accountability: a model cannot take responsibility for a decision.

Signs of Hype

Be sceptical of claims that a system is "unbiased", "fully autonomous" or "understands" in a human sense; of accuracy figures without a description of how they were measured; and of demos run only on the vendor's own examples.

A Practical Rule

Use AI where mistakes are cheap to catch and correct, keep people accountable for important decisions, and measure performance on your own data before relying on it.
