Closing the "change everything" gates would be amazing, from the standpoint of somebody that understands the value added by quality tooling and rules, after many years of experience, and moved on.
In unpaid OSS, having to repeat the same discussions over and over again is eroding at willpower that could be used for better purposes.
In workplaces, pushing for rules/quality in a post-factual society mindset/workplace can have really bad effects on your career.
Going back to the OP: yes, the average engineer is way below average quality.
It is not fixable: that's just how statistics work.
Every now and then, an incredible visionary (individual or group) will appear, produce something of exceptional relevance, and push the boundaries forward.
These visionaries will create their own tools, outside the boundaries of other tools, and will set their own rules/restrictions: they won't be worried about pre-existing rules anyway.
