I am getting tired of seeing physical building codes thrown around in comparison to software. I've looked at residential building codes, because I've done my own work like building a deck, framing and finishing my basement, and researching how to build concrete & steel suspended floors, or wood floors - seeing what their spans are - seeing how lightweight steel framing vs wood framing works - it's quite fascinating. (I was considering designing my own house, but the wife shot that down)

And there is simply NO COMPARISON in complexity to software. In physical building, you over engineer and get redundancy. You also know that almost everyone builds plumb and level, rectangular rooms, with easy span and shear calculations. You also know that wood follows a predictable strength pattern. So you put in enough nails of the right length, to enough wood of the right thickness, and you're good. How much intelligence do you think you need to follow a building code? Building materials and techniques change GLACIALLY compared to software. (A good thing!)

Whereas in software, one single bit flip will just fuck you up.
