Nothing humbles you more as a dev than seeing a layman struggle through an interface, getting increasingly frustrated and desperate because she can’t find the button she needs due to complexity and sensory overload due to a million tabs, buttons and text fields.
The worst of it is, you can see that she knows what she wants to do, but can’t translate that into the steps needed to get the computer to “understand” that, effectively making it feel as if it is trying to sabotage her. Something that would have taken 20 minutes with pen & paper suddenly takes 40 minutes digitally. Weren’t computers supposed to make us more efficient?
Considerately, screw your attitude. Eat some humble pie.
