I&#x27;ve built a bench and stuff like that before. Very comfy and reliable for many years now. And I don&#x27;t have any formal training in woodworking. It&#x27;s really not that hard. However, even after years of formal training in electrical engineering, you will struggle very hard to build a modern CPU. An attempt to compare the difficulty of the two appears to be ridiculous (I have also built a CPU, though only a very simple one on a FPGA. I don&#x27;t even want to imagine the amount of work and skill necessary to design a modern, say, Intel CPU).
