Look at how long it&#x27;s taken us to develop theories or technologies even after we had everything we needed to make them possible. The ancient Greeks had steam engines, but it took us millennia to start using them seriously. The concept of the engineering tolerance makes industry thousands of times more efficient; it could have been invented any time since the 16th century, but it wasn&#x27;t. The checklist has been known for decades to reduce errors across approximately all disciplines, but it still faces huge barriers to adoption. Evidence-based medicine has been the obviously correct approach since the invention of the scientific method but it&#x27;s still facing struggles. Even in science, we&#x27;re still arguing about the interpretation of basic quantum mechanics 100 years after the relevant experiments.
