Maybe, but the first thing you should think of is Elizabeth Holmes. May her legacy be that everyone is way more skeptical about the viability of any product.

What Theranos claimed to be capable of is physically impossible. Cursory technical knowledge of the industry would have made it obvious.

I would supplant your comment with, "Be skeptical of the viability of products that relevant experts are skeptical of."

I don't see the link between this and Theranos, your reply feels like an unsubstantiated dismissal of this research. This is a device that measures cortisol levels in your sweat, which apparently correlates well to the levels in the blood.
