>A consumer would learn this by having interest in the world around them

And where would they go to fulfil that interest? HackerNews? Or maybe, just consider it, the instruction manual that comes with the device?

>We don’t need cushioned guard rails on literally everything.

Sure. Just labels on self-exploding products saying that they may self-explode.

>When was the last time you actually read a product manual?

Yesterday. I got an Ikea ENEBY speaker. Your ignorance and lack of having interest in the world around you, which includes product manuals, is on you.
