Re: Mostly true...
An interesting reference, that. Unfortunately for many of us dementia isn't a matter of 'if', its more 'when', so we really need to be aware of it and how we can cope with it.
I have been interested in whether I could use a voice assistant ("Echo") as an interface. My model for this interface would be that of one of those CPR units that are designed for use by non-EMS personnel. ("HeartSmart" or similar). These devices talk you through the steps, cross checking that what it asks you to do has been done. The genius in their design is that they are designed to be used by people who are inexpert and -- obviously -- stressed. They're not going to read the manual and even if they did they'd skip or repeat important steps with potentially disastrous results. The machine won't let them. Now imagine a washing machine that talked you through the steps, cross checking each one. It is better than pure automation -- or a laundry service -- because it would give the person something to do, a purpose, which is at least as important as clean laundry.
