A lot of negative comments here but I could see some merits to this (supposing it’s in an open source context and the data doesn’t go anywhere)

For example, whenever you start to get stressed out, the thing will tell you to take a break. Little things like that. Instead of relying on your own level of mindfulness to get you there

I think that little things like this could definitely improve quality of life, something I’d pay for personally, although with the constraint that the data doesn’t go anywhere with zero exceptions
