I don't necessarily disagree with this if constrained to a narrow market segment. I have become fond of saying that reality can't be reduced to a single variable, it's a complex multivariate problem. I think I can say that most technical product sales do not depend on documentation. Some do. Some might, in part. Some not at all. Selling is interesting. I didn't think so many decades ago. I was forced to learn to sell once my startup finally had a product on the table. Literally. A hardware product. At first I sucked at it. I sold like I now recognize most engineers sell. It's terrible. I was terrible. I enlisted one of my good friends and resellers to train me. Within about eight months I was selling as well, if not better, than they were. The reason for this was that I knew how to sell at their level but could go hard-core technical when and if it was required (rarely). Towards the end I was able to sell our hardware without uttering a single word about the product. I'd show-up to a demo with the product, hand it to them, quickly help get it wired and then shoot the shit with the people in the room. Capable technical folk don't get you into a room product-in-hand unless they've done some research. Which means that you going on and on about the product is pointless. If they have questions, they will ask. I sold more product this way (millions of dollars) than by rattling off specifications, features and showing-off our documentation. I can't remember anyone ever asking me about the documentation. Your mileage may vary.
