KYC Automation for Scale and Speed

We've been grappling with balancing robust KYC compliance against the need for rapid client onboarding, especially in higher-volume retail segments. Automated identity verification solutions are attractive for speed, but I'm curious about the trade-offs experienced practitioners have found concerning false positives/negatives versus manual review. What are the common pitfalls when relying heavily on AI-driven KYC, and what level of human oversight do most find essential to maintain compliance without significantly bottlenecking growth?
