I learned this after I purchased a CNC for woodworking. A CNC is an amazing tool for so many jobs - and a horrible one for others. For some tasks, despite seeming repetitive and CNCable, manual woodworking tools speed up the process and the quality of the job.

An example: Adding chamfers to cutting boards. Sure, this could be done with a 45 degree bit in the CNC, but any deviation in board width/height/thickness means reprogramming the machine, and you can chamfer with a palm router in the time it takes just to affix the board to the CNC.
