A better-faith response would be to point out an example of such an open source codebase OR tell why that specific set of restrictions (open-source, active production, primarily AI) is unrealistic.

For instance, one might point out that the tools for really GOOD AI code authoring have only been available for about 6 months so it is unreasonable to expect that a new project built primarily using such tools has already reached the level of maturity to be relied on in production.
