Not just open-source hardware, actually hardware itself is hard, maybe that's why it's called 'hard'ware.
Digest thousands pages of datasheet, find the best price of the ICs, making sure no potential supply issue or long waiting time for the order, PCB, SMT, cost, more importantly quality assurance at manufacturing, logistics....
I would say it's 100x harder than software, been there done that.
