While it would be nice to be able to do this, sadly we don't have infinite resources, lest we be okay with actually shipping software in 5-10 years instead of 1-2. I know that I would be okay with such a world, but people who pay my salary might not share that point of view. Nor do the people who would have to choose an app to use in the near future, instead of waiting for a decade to do so.

The thing is, that the majority of the development out there is like the Wild West. If my code throws a NullPointerException or a NullReferenceException, then someone is going to be mildly annoyed and it might result in a Jira issue to fix. Code failing in a variety of ways is almost considered normal in some respects, outside of specific (expensive) contexts, where correctness matters a lot.
Admittedly, even in programming there are fields where the stakes are higher, though writing code for planes (as an example) is wildly different than what 90% of people out there would call "programming". Personally, I'd like 100% test coverage (lines, code branches, everything), but outside of these high stakes environments it would be wasteful to do so.
> If you have mot read your entire codepath, you have no idea what it is you are doing.
For many out there, this is pretty much impossible to do in a meaningful way. Let's use something like the Spring framework, a popular option in Java for web dev, a stack that has a rather high level of abstraction. In it, the actual code path that you're dealing with would involve your application code, the framework code (which is likely many times longer than your actual application, uses reflection and other complex mechanisms, overall being truly Eldritch at times), any integrated libraries, as well as the JVM and some other code on your actual system, that interfaces with the JVM.
Even if you toss out Java from the stack, the actual hot code path in any non-trivial piece of software will be pretty difficult to reason about, due to different types of linking, different external package versions etc. Unless you feel okay with very, very slowly stepping through everything with a debugger, which probably still won't give you too good of an idea of what's actually happening and what should have happened.
Though maybe traversing 20 layers of abstraction in Spring and coming out of that debugging session more confused than you were than when you entered it is just a Java/Spring thing, who knows.

I think there's plenty of misery to be had all around. For a humorous take at the state of things, have a look at this article: https://www.stilldrinking.org/programming-sucks
> All hail Time to Market!
All hail being able to pay rent by delivering sub-optimal software to meet ever changing business demands in an environment where nobody wants to pay for perfect software. That's simply the world we live in, take it or leave it (e.g. pursue whichever environment feels better to you, within the bounds of your opportunities in life).
