[Cumulonimbus]

Indeed.

I worked at a factory that had me do the following:

Put bracket in machine. Press button to tap holes. Repeat.

I got the loop down to about 3.85 seconds which was 115% faster than the engineers said I could do.

I found I could listen to audiobooks at that job. It still didn't stop the existential dread. I worked there for 2 months before finding a better place.
