I mostly agree, but I think it's important to note that when we talk about simplicity and complexity we're talking about hiding information first and foremost.

I mostly agree, but I think it's important to note that when we talk about simplicity and complexity we're talking about hiding information first and foremost. Keeping things small and straightforward comes naturally when all but the necessary information is out of consideration, because minimizing inputs requires factoring to the utmost degree, thus acheiving separation of concerns.
