When you go into a Target or a Walmart or certainly any small retail shop, everything in there was selected for inventory by a human buyer. When you read a newspaper, every single article was reviewed by a human before it was published.
Product designs are reviewed by humans for utility and safety. Drugs are reviewed by humans for efficacy and safety. Cars and trains and airplanes were human-reviewed during design and assembly, and again at regular intervals. Every scientific article is reviewed by humans before publication.
Systems that try to run at scale without human review have problems with quality. Amazon tries to run a retail platform with minimal human review; it’s choked with fakes and scams. Social media companies try to run with minimal human review; they’re full of false information and scams.
Why? This is actually one of the biggest complaints about the App Store review process, because it tends to produce a lot of inconsistent results if your app comes anywhere near the gray areas of the App Store guidelines.
Mandating human review for everything sounds like a good idea for those who imagine perfect, highly-skilled, consistent reviewers handling every step of every process, but that’s not how things work in the real world. You don’t actually want to legally mandate real humans handling every step of everything, unless you want to force everything back to the days of bureaucracy and endless back-and-forth communications to get everything done.
