Interesting thoughts. I like the idea of nano medicine.

My 2 cents

The first stage will be using existing sensors to gather and process the information properly. This will be taking all your blood tests, scans, diet, symptoms to create personalized recommendations, mostly proactive.ideally also input your entire genome to help predict issues.

Then we will have new devices that AI helped created. I'm guessing mostly sensors to monitor your body and perhaps customized nutrion/probiotics. Basically just accelerating to market things that are already in the works.

Then we get into the real interesting stuff. Once AI has ramped up properly and can integrate itself into the manufacturing, then you get BMIs that can let you workoit harder, control your emotions better, treat a variety of mental illnesses, etc, customized mRNA for anti aging, enhanced physical and mental abilities, customized hormone production, etc. Far more detailed monitoring that can likely react with dosing of hormones. And likely automated hospital stations that can do detailed scanning and treat anything from a cavity or minor bruise to surgery.

All automated at the cost of materials that were created by robots in the first place. Imagine an AI picked up on some detail, recommended you get a scan, find a cancerous little group of cells, get a customized mRNA shot, and the cancer is gone.

Vs traditional medicine now which will look like the dark ages...!
