Your second paragraph is the impetus behind Agile Software, and we've all seen how fantastically that failed. Lots of code pushed out quickly, but also a lot of really shitty products, uncertainty, never-complete projects, dysfunction between teams, etc.

No, but it does impact people's lives significantly. How many times has your personal information been leaked by a company making products by people who didn't care? Who would have predicted that a security company's terrible QA would lead to 8.5 million crashed systems, 42,000 delayed flights, 10,000 cancelled flights, and over $10B in economic losses? I'm sure the developers just said "not our problem". But their lack of concern, and "just throw shit at production" mentality, had real world consequences.
