This is a great point.

We saw this emerge with the so-called digital signatures and PKI which purported to allow humans to sign contracts digitally. But nobody could do RSA maths in their heads, so we ended up having to trust the tech. Which led us down the garden path building more and more complicated trusted thingummybobs. Until ... we discovered that they were too complicated to use and users just ignored them.

So I like to ground such discussions in real users, not to fall in that trap again.
