How artificial intelligence drives PPC automation

From the 1970s through today, there have been three waves of technology innovation in the Silicon Valley that have spawned many industries, including ours (online marketing). First, there were semiconductors, then personal computers, and most recently, the internet. Now we're on the cusp of the next wave of innovation, driven by advances in artificial intelligence (AI). Given that our industry exists thanks to these waves of innovation and that automation -- a top trend in PPC for 2017 -- can be driven by AI, how might things change for us during this next wave? And what risks do we face when we start to use far more automation without knowing the extent of its abilities?
