Did Complex Flight Feathers "Emerge"?

Here's a thought experiment. Consider something you know is intelligently designed: for example, software code for an app that flies a drone. Now let's describe its "emergence" in Darwinian langauge:

Once assembly language emerged, it diversified into logic gates of increasing complexity, as crawling robots co-opted various functions for novel adaptations, including powered flight. The coding mechanism driving this spectacular process remains unclear. Through morphological analysis of robots...
