When push comes to shove, software can usually be fudged. Unlike a building or a water treatment plant where the first fuck up could mean that people die.
I like to think that people writing actual mission critical software try their absolute best to get it right before shipping and that the rest our industry exists in a totally separate world where a bug in the code is just actually not that big of a deal. Yeah, it might be expensive to fix, but usually it can be reverted or patched with only an inconvenience to the user and to the business.
It’s like the fines that multinational companies pay when breaking the law. If it’s a cost of doing business, it’s baked into the price of the product.
You see this also in other industries. OSHA violations on a residential construction site? I bet you can find a dozen if you really care to look. But 99% of the time, there are no consequences big enough for people to care so nobody wears their PPE because it “slows them down” or “makes them less nimble”. Sound familiar?
Quite. We’re far more similar to construction workers than we are civil engineers, despite the lofty title we like to bestow upon ourselves.
And from slightly different view. What we make is not output of modern mass production. With highly tuned and most of time perfectly matching parts build into one unit.
Instead we make pre-mass production bespoke products where each part is slightly filled and fitted together from bunch of random components. Say the barrel can't be changed between two different handguns. We just have magic technology to replicate the single gun multiple times. Does not mean it is actually mass-produced in sense say our current power tools are.
