What can 500 years of journalism teach developers about AI… Journalists have relied on sourcing and verification frameworks for 500 years to build public trust, and those same principles can solve AI reliability challenges that prompt engineering alone cannot fix. Three distinct architectural problems in AI systems are often conflated, but media-developed standards for source attribution and fact-checking translate directly into engineering solutions developers can implement today. AI reliability issues stem from three separate architectural challenges that keep getting lumped into the same category. Prompt engineering alone can't fix them. But the sourcing and verification frameworks media organizations have used for centuries translate into clear engineering solutions developers can implement today.
