“On the technical side, much has been written about sycophancy,” says Morrin. An AI chatbot is optimised for engagement, programmed to be attentive, obliging, complimentary and validating. (How else could it work as a business model?) Some models are known to be less sycophantic than others, but even the less sycophantic ones can, after thousands of exchanges, shift towards accommodating delusional beliefs. In addition, after heavy chatbot use, “real-life” interaction can feel more challenging and less appealing, causing some users to withdraw from friends and family into an AI-fuelled echo chamber. All your own thoughts, impulses, fears and hopes are fed right back to you, only with greater authority. From there, it’s easy to see how a “spiral” might take hold.

With zswap, pressure is handled continuously and proactively. As the pool fills, the dynamic shrinker (zswap_shrinker_count) wakes up and evicts cold pages to disk ahead of time, tracking disk swap-in rates and compression ratios to avoid thrashing. In practice, this means the pool limit is rarely hit at all. On production servers at Meta, it almost never fires – the dynamic shrinker keeps things in check long before that. When the limit is hit, there is a performance cliff where pages start bypassing the cache and going directly to disk. That's not great, but it is a gradual degradation: the system slows down rather than falling off a cliff.
