My company went public and was acquired, all while doing basic database shit hilariously wrong and just strapping in memory caches everywhere instead of using indexes. We have two caches and we really just needed to use the dB in a not criminally bad way. But the market didn't care and the people who did the abuse are now director or architects or manager level engineers at other (good) companies. There's some reality that knowing this stuff matters but it honestly doesn't for a huge number of tech startups, at least in this market.
