Think of communications as algorithms, a collection of proven plans or instructions to help get you from point A to point B.
Say your organization is having an image problem around a specific issue. You hire a professional communicator or public relations expert to come up with an "algorithm" -- a plan, a solution, an idea -- that takes specific variables and formulas as given realities and then goes to work.
It used to be that the notion of an algorithm was around speed and efficiency to get around a mathematical task or problem. Like, say, sorting numbers in a particular order in less than a nanosecond, like this sorting algorithm at work:

So, look at our world today, and the digitization of our "social" life (think Facebook, Google, etc.). No longer is digital helping us crunch the numbers, it is now an intermediary between our own selves.
As our social lives continue to depend more and more on machines run by algorithms, how are the algorithms assuming what you and I are all about? How are the machines figuring out how we need to be communicated to or with? What biases do they think we have and prefer? How do they help us, or not help us, unlearn biases? What is the overall purpose of specific "social" algorithms?
I don't know the answer, but this video made me think of that.
