The importance of QA

Can you please explain what this is supposed to be?!

At first I thought it would be like in the scene in "Idiocracy" – adults unable to map 2D←→3D shapes

I hope this embedding these downscaled and heavily compressed movie images is within "Fair Use". Just for illustration purposes.
I recommend buying that movie!

My second thought was that the box/lid was badly designed/manufactured (by that women that seems to try hard not to start crying).

At last the video description states she's an actor.
=========

Maybe I'm the idiot here and openly confess: I don't understand this.

The design is severely flawed. Something like this is meant to be a teaching tool for toddlers (or younger), but it should be designed in a way that it is impossible to fit the wrong shape in the wrong hole. The QA guy was demonstrating to the engineer, how she failed at this.

The importance is that this applies to pretty much everything, including programming. Without preventing unintended uses, you get buffer overflows, leading to privilege escalation and code execution. You get things like all of the glitches in every Metroid game. Metroid Dread added Easter-eggs, fully intending people to find sequence-breaks... but I guarantee you that they never intended for it to be possible to phase down through a floor... (as an example).

I think what he's trying to show (with a bit of sarcasm), is that almost all of the shapes can fit & go through the square shape (major flaw) , which means that this "thing" fails to do its job properly. Well at least he didn't show us that ALL the shapes can go through the circle..
