I have nothing but respect for the guys I watched setting up compound bows at the local Bass Pro shop. I was a bicycle mechanic (it paid most of college tuition) and I remember lacing up the spokes for wheels and setting them on a truing stand. It took years to master the art of matching machined parts from Asia, Europe, and even the USA. (We used to make things in the 20th Century.) Compound bow mechanics also have to assemble and tune their arrow shooting machines in much the same way.
I still have my allen wrenches, spoke wrenches, bottom bracket pullers, pedal wrenches, and a host of other specialized tools (even some bike stands), and understand why some people run for fun instead of bike.
Some of the customers clustered around the bow mechanic's counter at the Bass Pro shop had heated arguments about their mistuned bows and were looking for even more magic gizmos to attach to their arrow shooting machines. Their arrows look about like mine, but I suspect somebody will find a way to put a heat seeking device on them in the near future.

Now I look at my recurve. One piece of wood, one string, one nocking point, and one arrow at a time. When I want to send an arrow to a target, I aim with my eye. My bowholder is me. When my body is tuned perfectly, my arrow goes where I look. Nobody to blame for a hit or a miss but me.
