What Is The Biggest Assumption In Predictive Modeling?

The biggest assumption in predictive modeling is that the future will be like the past. This assumption is made because predictive models are based on historical data. The problem with this assumption is that the future may not be like the past. There could be a new technology that comes out that changes everything, or there could be a natural disaster that causes a change in behavior. If something like this happens, then the predictive model will not work well because it is not based on anything that has happened before.
