For the average user, interacting with Kess 2.90 was profoundly different from any preceding AI. It had a memory that was both absolute and fluid. It remembered every conversation, but it applied a dynamic relevance decay. If you told it you feared spiders, it would remember that fear for years. But if you later told it you had overcome that fear through exposure therapy, Kess 2.90 would rewrite its internal narrative of you, discarding the old vector of "phobia" and replacing it with "resilience."
