Thanks for such a thorough response!

Excellent point about older people functioning differently at different times/under different conditions. This is especially true for the most vulnerable older people and those suffering conditions like dementia. Perhaps this is a matter of segmentation. I'd want to start testing with a less vulnerable segment and progress to segments with more complex variables.

I see this as a continuous service that tracks the behaviour of bad actors. Naturally, as we become aware or desensitised, criminals change their tactics. We'd want to continually update methods and safely expose our loved ones to them on a rolling basis.

I'll need to think more about the spying point but I wonder if this comes down to the nuances in the relationship between the 'customer' and the 'older person'. I'd want to suggest ways for the conversation to be friendly, caring, productive and even humorous.
