Algorithm

I was driving up north to Lake Ann for one of the quarterly board meetings at camp on which I’m privileged to serve. I listened to a podcast about artificial intelligence on the way up, and something he said caught my attention. The expert said that there are now boards of directors on which they are placing a robot as a voting member. One of the seats is actually filled by an algorithm. He (it) gets a vote - just one - but it is a real, participating member of the leadership.

The speaker said that certain algorithms are actually more skilled than people, especially in functions where non-emotional analysis is required. An algorithm can actually read an x-ray searching for signs of lung cancer more skillfully than a human technician. It is able to rapidly analyze each of the pixels of the photograph, looking at the picture differently than we humans tend to do.

Clearly this doesn’t apply to all roles that humans fill. Humans are better at considering situations from different points of view, and integrating ideas from a variety of disciplines. But, humans also tend to over-estimate their objectivity, and that’s where the algorithm shines. It doesn’t get bogged down in the emotions or subjectivity of a case.

A couple more things: Many such algorithms (robots) are now self-learning. That is, they analyze their own performance and the performance of others, and improve over time, rapidly, so that they write new algorithms that are better than before. They are self-improving, and don’t spend too much time denying that they have previously made a poor judgment, unlike you and me.

And then this: scientists are now designing “master algorithms” that are able to take the work and results of many algorithms with a range of responsibilities, and to unite them into a cooperative force that will address more problems. The scientists know that they will soon not be able to even understand all the conclusions that the algorithms will write. I guess we will then just have to trust them.

Other than looking around the room tomorrow wondering which one of us is really more algorithm than human - I had to wonder if God is not a little like the master algorithm - the one who is able to direct all that goes on from a superior position. But no, God is not a piece of code. For one, He is never-learning, in that He already knows all, and holds all knowledge at once. He does not figure things out, because He already knows. He holds secrets, but He also graciously reveals. And we know we can trust Him.
