When Salesforce unveiled sales forecasting with its AI tool, Einstein, my immediate reaction was that it should have tried something easier -- like solving global warming. A sales forecast that bears some resemblance to reality has been a grail quest for all of us for many years, and Salesforce is not the first software company to throw its hat in the ring. It's not that the company should have tackled an easier problem, but that the success of a sales forecast is inversely proportional to the amount of human involvement in producing it.
