Frankly, I think self, or at least at home diagnosis, IS the future of health care. Med tech needs to be sold at the consumer level and incorporated into the daily hygienic routine, in a non intrusive way. The bathroom of the future will have diagnosed this problem. After you take your morning piss, or crap in in your space toilet, it will analyze the contents and report back any, uh, interesting findings, proposed causes, solutions, possibly give the option of scheduling an appointment with a doctor, etc.
Hell, doctors are ALREADY being giving PDAs with diagnosis software based on data mining techniques. Type in the list of symptoms, and let the program compare with a repository of data to kick out a diagnosis. I think we're heading to a point, probably still in the far future, where "doctors" in the traditional meaning are irrelevant. They will probably be needed to perform actual procedures, or to diagnose more complex sets of health issues, but for simple "analysis" of basic or common, health problems, machines in every home will be plenty sufficient, as well as add the benefits of early warning.
However there will probably be obstacles in the way of moving med tech to a consumer product for self diagnosis in home. Namely various doctors/medical associations that are looking out for their own interests, and busybody government buerocrats seeking to "protect" you from the possibility of self-misdiagnosis while actually protecting the profits of a somewhat marginalized profession.Similar to what we see happening in every industry where tech marginalizes former moneymakers...
Anyway, good for this girl!
Now make me a space toilet!
