I laughed. Funny cartoon- in all seriousness- “why” isn’t often as important as “what.” Why can be useful in making decisions- if someone begins to savagely beat you- what is of more practical importance to realize and address- why they are doing it, or that they ARE doing it? “Why” and “how” are questions of mastery. I can tell you why we invented airplanes. I can tell you how an airplane works- mechanically- the physics of it... but if you suddenly found yourself teleported alone into a plane in flight- what to do to not crash in that moment is priority 1- go to flight school if you land and learn the rest later- but you don’t need mastery to fly a plane- it’s just very advisable.
The same reason we make robots: just because we can.
