I hate that in our industry we refuse to operationalise reverse debuggers "I never understood the code. You think it works a certain way, until you find out that it doesn't." Bret Victor made a talk called "seeing spaces" in 2014 that should have woken up this whole industry: https://www.youtube.com/watch?v=klTjiXjqHrQ He emphasizes that without the ability to see inside what is being built, creators often fall into "non-scientific thinking" (14:42), moving away from deep understanding and instead "blindly following recipes, from superstitions and rules of thumb" (14:47-14:51). The worse is performance problems I've had engineers say some bizzaro things when discussing performance — we have the tools you can just measure the answer - we don't need to waste our time guessing
