We will reach Peak Training Data in the next five years, where you can't improve the model by feeding it more training data because you're already using everything worth using.
@WomanCorn This feels quite true to me. (Where "new paradigm" could also just be "better activation function found").
We will reach a point of diminishing returns on increasing parameters within the next 20 years, where the cost of hardware to increase parameter counts isn't worth the increase in value you get from the model.
