I think there's 2 things here. One is the thought reading process to create automatic reminders and the other is accurate location tracking in small and indoor areas (like your house).
The second thing can be solved already but requires more than GPS, you'd need a supporting infrastructure in your house (I think this is set up in some shopping centres/malls).
The first thing is a little more futuristic (like you I am sure it's being worked on) but in the interim maybe a 70% approach would be educated guesses based on past behaviour which could be collected over time? E.g. what did you do the last 3 times you went to the bathroom at this time and in this way (i.e. the path you took, the speed you went, etc. etc.) there's a heap of data that could be collected if you wanted and some smart algorithms could make reasonable guesses. Maybe Cortana can even tell you to go to the bathroom before you realise you want to, or maybe that's a step too far...
