> New features and better UX is more useful for the users of many systems than fixing tail frequency bugs If nobody notices a bug, does it matter? There's whole classes of technically bugs that simply never happen under the real world operating constraints of a software system. The infamous example is that memory leak story from the Microsoft blog[1] – you don't need to fix memory leaks on a rocket that goes boom (or runs out of fuel) after 5 minutes of flight time. Just add the extra memory chip and move on. Engineering is all about building to real world constraints. Don't build a suspension bridge where a sturdy plank will do.
