FWIW, "feel" and "good" as used in this article is not about emotions; it's more of a shortcut that means "Do I trust that this is doing what I expect it to regarding (safety | stability | understandability)?"

"Feel": "I trust."

"Good": "Does what I expect it to."

"Trust" is (or at least can be) an emotion.

Trust is the faith that the subject won’t betray you or your interests despite being in a position to do so.

It’s a belief, not an emotion.

Hmm, yeah, good point. I think you're right.

I guess the emotions associated with trust might be "peace" or "confidence".

Thanks for correcting my error!
