It's tempting to just let tools think for you, but you still need to be able to think for yourself and stay sharp.

Great idea. My favorite API response so far: "I didn’t receive the memo that I was supposed to care." 😆
Are you a people pleaser who doesn't know how to say no?

Das ist das Instagram-Profil der Kanzlerpartei in Österreich. Ihnen geht es längst nicht mehr um die (notwendige) Bekämpfung des Islamismus: Sie wollen absichtlich Ressentiments gegenüber allen Muslimen schüren.
