Quote:
All organs are made of cells, which are made of organelles and membranes, those are made of proteins and so on, etc. The fact that they function in complex systems is the result of many small incremental changes--as hard as it may be to believe.
I've been coding too long, this quote reminds me of Test Driven Design. 
As far as technology needing a designer, even that isn't always true. I've written simple programs that, when executed, write their own programs that, when executed, write their own programs... In this way, a simple set of commands can "evolve" into something so complex that the original programmer can't figure out why it works.
