True simplicity is derived from so much more than just the absence of clutter and ornamentation. It's about bringing order to complexity.

--- Jonathan Ive, explaining the design philosophy behind iOS 7 in the product video shown at WWDC 2013 (according to Wikiquote) (h/t Agata Toromanoff for the quote in her article Conscious Environments about Elena Mora, Aesthetica Magazine, June/July 2018)

From Wikiquote:

I think there is a profound and enduring beauty in simplicity; in clarity, in efficiency. True simplicity is derived from so much more than just the absence of clutter and ornamentation. It's about bringing order to complexity.

You can’t run, and you can’t hide from complexity; there’s no point in even trying

Quote in context

You can’t run, and you can’t hide from complexity; there’s no point in even trying. You’re going to encounter it; ignoring it doesn’t make the problem go away, it just allows the problem to fester under some “rug” in some corner of your network. The complexity problems you create today will return as bigger, more complex problems in just a few years.  

… 

When dealing with engineering problems, then, a little humility around what can, and cannot, be solved is in order. Don’t ignore complexity, but don’t think you can solve it, either. Instead, remember to treat every situation as a set of tradeoffs—and if you don’t see the tradeoffs, you’re not looking hard enough.
