I was considering enabling it, and I could see the features being useful for some people, but not for me.

For example, notification summaries. If someone has apps blasting them with notifications, summarizing them into fewer more meaningful ones could be truly helpful. But for me, I’ve carefully managed my notifications. I get almost none. Every single one that is enabled is important and actionable. I don’t need to summarize what’s already small.

The writing help is another example. Maybe a person is a slow typist. Maybe they are losing a lot of time thinking of what to write, or how to word something. Maybe they are writing in a language in which they are less than perfectly fluent. In those cases the Apple Intelligence can be truly helpful. None of those are me, so I disabled it.
