I look at that as the efficiency distinction. It goes without saying that if we had more time, there would be fewer bugs. But there are also things (tooling, automation, code development processes) that can decrease the amount of bugs without ballooning development time. Things that decrease bugs_created per unit_of_development_time. Automated test suites with good coverage, or KASAN [1, mentioned on here recently]. Code scanners, languages that prohibit unsafe development operations or guard them more closely, and automated fuzzing too.
