I design, implement and support contact centers for a living (think Avaya, Cisco, etc..). For the past five years, we've been preparing ourselves through education and training for this omnichannel take over of voice. While other channels have taken some of the voice pie, it's not nearly as significant as those of us in this field thought it would. I've created chat bots, IVRs and everything in between for automation, and people absolutely hate it and simply want to talk to a human. Most customers push going to the website, but the problem is that a lot of people don't know how to navigate properly. To help this, a lot of customers implement co-browse into their chat solution, but that's only helped a little. We too are using Google's Dialogflow and I'll be looking to deploy my first one in a couple months - very promising compared to other solutions out there like Amazon Connects Lex Bot. Regardless, leaders and technology evangelists in this field still preach that by 2025, the overall percentage of the pie for voice will end up being about 15%. But they emphasize that those humans who make up the 15% will be the most important in the customer service/support space.
