19 The future of AI
This chapter covers
- The limitations of deep learning
- The nature of intelligence
- What’s missing from current approaches
- What the future might look like
To use a tool appropriately, you should not only understand what it can do but also be aware of what it can’t do. I’m going to present an overview of some key limitations of deep learning. Then, I’ll offer some speculative thoughts about the future evolution of AI and what it would take to get to human-level general intelligence. This should be especially interesting to you if you’d like to get into fundamental research.
19.1 The limitations of deep learning
There are infinitely many things you can do with deep learning. But deep learning can’t do everything. To use a tool well, you should be aware of its limitations, not just its strengths. So where does deep learning fall short?
19.1.1 Deep learning models struggle to adapt to novelty
Deep learning models are big parametric curves fitted to large datasets. That’s the source of their power – they’re easy to train, and they scale really well, both in terms of model size and dataset size. But that’s also a source of significant weaknesses. Curve fitting has inherent limitations.
