But it’s actually not impossible to create your own CPU from scratch. I’d suggest starting off with a $50 or less FPGA and start learning about the logical building blocks of a modern CPU. You can then advance to building up a basic CPU fairly easily. Creating a full featured ISA and then designing out the circuits and having the chip actually fabbed is not trivial, but I know of many hobbyists who have, so it’s certainly doable if you’re dedicated enough.
