Pros and Cons of Keeping Written Records
There is a difference between ability to do something and the need to do something. Everyone should be capable of understanding of why records need to be kept.
Pros on Keeping Detailed Written Records
Written records are a way of having people who no longer exist to provide information. It also allows replication, it allows you have the same project be done by someone else and get done again. Ex. Good open source kits have step by step instructions. This allows people to have desirable variations. Same thing on construction, people have instruction on building a colonial and a ranch. With good instructions, they can create a combination of the two.
Cons of Keeping Written Records
There is a reason not to write detailed records, in business, there is something called business retention policy. Well run businesses destroy written records. There is liability for something that is done when you do not have records.
