Sure tests cost money - and today there is a funnel pathway - the educated guess is a funnel/filter where the next step which is often a biomedical test/investigation.

But if we are talking about being truly transformative - then a Star-trek tricorder is the ultimate goal, rather than a better version of twenty questions in my view.

So I'm not saying it's not useful, just that it's not the ultimate solution.
