I'm right there with you though, I bet the tricorder has a nose not a eye.
And I wonder how people like Holmes are able to survive for >10 years. We can deliver nicotine via patch, so obviously all drugs should be delivered that way. We can measure glucose from a drop of blood so obviously it follows that all blood tests run that way.
Where is the evidence that even a small fraction of the most common diseases have such a characteristic?
"Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith."

The further issue diagnosing cancer/no cancer or epilepsy/no is an easy problem. But train a dog/machine on 1000 or more rare diseases. Now selectivity is an actual issue. And unless you manage to overcome that, how is all this scent stuff clinically useful?
I also dont understand how training a machine would have selectivity issues. Machines dont "get trained" on one thing.
