Those guys had to have unions to fight for safety practices. It's to protect the workers. This code quality stuff is about various competing business objectives and now annoying stuff is.

I've never seen a programmer be dismembered from a missing test though I'm sure such things happen in embedded systems and robotics. Tesla Autopilot or the Uber self-driving accident in Arizona are great examples of programming leading to deaths.

I guess if your Uber app doesn't work in the rain that is bad. It's when people are making safety critical decisions that this stuff matters more.

RAM and CPU usage is not an opinion.
