This is true only for a small subset of problems. If you write crypto or hardware drivers, details do matter.

The great reveal of LLMs is that our systems of checks and balances don't really work, and allow grifters to thrive, but despite that most people were actually trying to do their jobs properly. Perhaps nothing matters to you except the most shallow approximation of a thing, but there are usually people harmed by such negligence.

I think the exact opposite is true: LLMs revealed that when you average everything together, it's really bland and uninteresting no matter how technically good. It's the small choices that bring life into a thing and transform it from slop into something interesting and worthy of attention.
