LLM quality drops aren't disillusionment either - it's scale/cost optimization. And those are subscription models - Siri/Google assistant is bundled with device/services.

Coincidentally, those features were degraded so that those companies would have more compute power available to do inference for their LLMs

> Siri/etc aren't just general disillusionment though, people often talk about features that have been removed and replaced with a web search.

Recall that recently Google removed the image generation feature from Gemini after the diversity controversies. :-)
