The human part is a data annotation part, something which helps us move towards full automation. There is obviously no way a human operation will ever get to the end of those ~10 Billion formal meetings being scheduled in the US every year. Heck, we might die trying to fully automate this and we are certainly not finished yet, but I think we are off to a good start and we are fighting for that 100% Automation goal every single day. Feel free to email me if you want to join 24 other propellerheads on that mission :)
