The human brain's real bottleneck isn't storage capacity—it's bandwidth. We're not limited by what we can remember, but by how efficiently we can discard irrelevant data. Think of it like garbage collection in memory management: the system that prunes useless information faster wins. This has massive implications for how we design AI systems that interact with humans—optimize for attention filtering, not just information delivery. Our brains are already running aggressive compression algorithms 24/7.
