I think the author comes from a very specific perspective; RAD tools, as I understand it, generally has only one, or a very few, software engineers per product.

I think the author comes from a very specific perspective; RAD tools, as I understand it, generally has only one, or a very few, software engineers per product. The way I would write code on a personal project is very different than the way I’d write code in an environment with changing team members, interns, guest commits, etc. Also, In real-time simulations (ie games) often then way you write code can be the bottleneck. In web services the bottlenecks are more often network calls, database model, etc.
