expressive enough for general-purpose generative tasks. Generating human-level writing or code remains a pipe dream. 
Wave 2: The race to scale (2015-Today) A landmark paper by Google Research (Attention is All You Need) describes a new neural network architecture for natural language understanding called transformers that can generate superior quality language models while being more parallelizable and
requiring signiﬁcantly less time to train. These models are few-shot learners and can be customized to speciﬁc domains relatively easily.
