- The path from transformers to ChatGPT (2022) took about 5 years.
- Children learn object categories (e.g., 'cat') through experience and probability judgments.
- AI, like humans, learns by identifying patterns and making probabilistic assignments.
- Example: recognizing a cat from a tail based on context and learned data.
- Early AI relied on explicit rules (e.g., identifying indoor furniture to infer 'cat' over 'fox').
- Modern AI learns contextual associations from massive datasets.
- The sheer volume of data allows AI to infer likely scenarios (e.g., a tail indoors is likely a cat's).
- The next step in AI intelligence involves understanding motion and interaction (e.g., a cat moving towards a mouse).
- This capability emerged when video data was incorporated into training sets.
