I wonder if part of the "no big deal" view comes from the difference between tech companies as they're most visible now - 'move fast and break things' - versus all the other industries that rely on computers. It's easy to imagine a lot of tech companies today taking a 'fix on failure' approach, because they're built on the idea that you deploy changes quickly, so they can accept a higher risk of faults. It's harder to make changes in banks, airlines & power stations, thus they're more risk averse, and far more likely to invest resources in the kind of effort the author describes to find & fix issues in advance.
