These days there are many work places where people don't have enough skill finding and fixing "bugs". People used to copy and paste Stack Overflow answers into the company code base until it "worked". Then if there was a problem it could sit for weeks or months with someone and then moved to another person. It's interesting because in most cases doing simple prints just to see what's going on could give a hint what to fix, but even that was too complex. It's getting worse because if software is making money then there is further incentive to cut costs of development (hiring less experienced and cheaper engineers) and corners (let's not do TDD it's a waste of time). UK government is addicted to big consultancies that are famous for this and they have been exploiting public sector by delivering half arsed projects (if at all) at extremely high cost while tasking cheap and inexperience labour to do the work and pocketing the rest of the money. There is no organisation interested in investigating all those contracts.
