I woder wether this will have the same pitfalls as regular ChatGPT.
The latter implicitly assumes all your questions are personal. It seems to have no concept of context for its longer term retentions.
Certainly for health, non accute things seem matter a lott. This is why yoir personal doctor that has known you for decades will spot things beyond your current symptoms.
But ChatGTP will uncritically retain from that time you helped your teacher relative build her lesson plans that you "are a teacher in secondary education" or that time you helped diagnose a friends car trouble that you "drives a high performance car" just the same as your regular "successfully built a proxmox datacenter".
With health there will be many users aking on behalve of or helping out an elderly relative. I wonder whether all those 'diagnoses' and 'issues' will be correctly attributed to the right 'patient' or just be mixed together and assumed to be all about 'you'.
