LLM AI is a fad, but not the same kind of fad as VR. It doesn't need to be integrated into everything, but the technology has genuine utility and will not be going away.

I think the trend for "AI in everything" is stupid, yet I'm running a Vscode plugin that integrates local LLM models and it's very useful.

This is the same sort of thing that can be useful in a browser too. The web is so spammy these days that feeding it to an LLM to summarize and filter it is a legitimate use case.
