What job is useless?

My "job" is pretty useless. My thesis professor asked me if i wanted to join this project going on in the university in collbarion with a tech company, i wasn't doing anything (long story) so i said yes. My job consists of manually assembling all the parts that make the product this company is selling until the demand becomes high enough to the point it justifies spending more money on machinery to replace me. I'm finishing an engineering degree and i work with folding some papers and putting buttons in the right places. It's not like i'm not thinking about my future past this but given the situation i was in I'm pretty grateful for this "Job".
