As the world goes more towards digital content, the more robots/AI/software will do the marketing. The growth of Facebook revenues is a clear indication that software is better at marketing than humans. They know which buttons to push and when to get the right response. They know you better than the marketing manager at company xyz.

Marketing automation is already here and its only going to get bigger and better. The sales and marketing teams will shrink to 1-2 persons even for large corporations. They will make us more efficient.
