I totally agree. Non-invasive diagnostics will be the future. There is a lot of information in speech, gait, eye-movement, general appearance, pulse - TCM used these information to assess the health condition.

I am confident that one day the gadgets like VR, Apple Watches, smartphones and general video information will warn when health conditions change and recommend proper steps to reverse the process before severe health issues.

But it is a long road ahead, limited by capital.
