"Behind this possibility lurks a larger vision, too. "

And a much darker one.

I for one, do not want machines scanning my heart-rate, pupil dilation, breathing pattern, muscle micro-movements, facial micro-gestures, etc, while in interview, for example.

These technologies are of course being developed for the purpose of control, for example in interrogation, and not for the benevolent purposes they claim, IMHO.

The PTSD victims they give as an example use-case, should be treated with humanity, not sniffed out like rats with technology, to then be subjected to institutional corrective treatments.
