Cognitive Monoculture Problem in AI Agent Systems

Everyone's building AI to replace employees but is missing something: companies succeed because different employees with different thinking debate and merge into better outcomes. If all your agents run on the same LLM, you've killed that variability. Even across different LLMs, training data overlap is massive. Even after giving each one it's own markdown file with a fake personality, you're getting the illusion of diversity. This will become the cognitive monoculture problem in AI.
