I'm not a doctor, but a technologist. A new diagnostics tool? Good! But I can guarantee that good doctors won't ditch the stethoscope for anything else. No amount of automation can replace the reassurance that your own senses give you.

This is perhaps more true in the case of mechanical engineering. The touch and feel of the machines can be unfamiliar and changing. And the diagnostics tools are more available (because invasive probing is more acceptable). Despite this, I have noticed that myself and others depend on sight, sounds, heat and sometimes even smell to keep a tab on their health. I don't think any professional would consider completely cutting off their own senses.
