Sean Riley

Sean Riley is a filmmaker and editor whose Computerphile videos cover AI and computer science. In May 2016, Brady Haran credited him with making nearly all of the channel’s videos; by 2021, Riley was making its videos after broadcast software work around the world and television news directing at BBC Nottingham. He edited a 2023 Sixty Symbols film built around a quantum-physics metal song, worked with Matt Godbolt on CPU fundamentals episodes they began recording in late 2023, and filmed Computerphile’s DeepSeek episode in January 2025. In April 2026, he filmed and edited the channel’s post-quantum cryptography episode; as of October 2026, he continues to film and edit its releases.

  1. The company share of AI researchers’ top papers was 31% in 2020–2024 and 8% in 1970–1974Includes British Broadcasting Corporation. We estimate where the people shaping AI worked when their most-cited papers appeared: the company share was 31% in 2020–2024 and 8% in 1970–1974, and Google led all organizations in 2020–2024.
  2. Google had the most people shaping AI every year from 2014 to 2025Our estimates of which organizations employed the most people shaping AI each year from 1955 to 2025, tracing the shift from university labs to companies.
  3. The United States employs an estimated 48% of people shaping AIWe estimate where the people shaping AI work today, how universities, companies and research institutes split across countries, and how country shares have changed since the 1960s.
  4. 43% of living people shaping AI work outside their country of birthWe estimate that 43% of living people shaping AI work outside their country of birth (520 of 1,198 people with known birth and employment countries).
