It's important to make sure that what these algorithms actually produce is surprising to subject matter experts. I can recall, but can not find at the moment, a tumblr post where the blogger was surprised that a computer program which optimized a physical structure to minimize material while maximizing strength ended up looking organic. This didn't surprise me at all. Organic structures evolved over millions or billions of years and probably are nearly optimal at accomplishing a particular task. I'd be surprised if the optimization software didn't produce something that looked organic. It's not like the optimization software was better than actual organic structures either, which are neither isotropic (in organic structures the strength varies depending on the direction) or homogeneous (in organic structures the strength varies depending on the location) as the software had assumed.
