Knowledge does not grow indefinitely. It is in itself a system physically embedded in other systems, like society, individuals, records. Human minds can only contemplate a small subset at a time. Maybe a Uber-AI might do better. System interrelations get stymied by complexity and physical trade-offs, antagonistic relations. Existing knowledge concepts ignored by article include biosphere systems collapse, global heating, mass extinctions, resource quality pyramid, entropy law, Seneca collapse, population cycles. Every new technology has its dark side, so does human nature, because we live in a system of systems. Article fails to handle concepts of scale vs quality. Sure human knowledge will keep growing. All the new and different ways we can crash the systems we depend on.
