Do you remember grade school at all. Endless busy work. Teacher hands out a worksheet, any worksheet, just an endless stream of pointless word searches, fill in the blanks, answer these instances of x+y=_ , color by number, write a paragraph in this box, draw hands on this clock etc. Let's be real, below around 8th grade school is mostly socialized babysitting, and these worksheets are in large part there so teacher can keep you all preoccupied with literally anything. Its all equally tedious and just as pointless as say, adding captions to stock photos or pointing out all the traffic lights in an image. The difference is one of them pays and the other doesn't.
