Conclusion Large language models have initiated a significant change in the scope and quality of program code that can be automatically generated, compared to previous approaches. Experience with commercially available tools built on these models suggests that a they represent a new way of programming. LLM assistance transforms almost every aspect of the experience of programming, including planning, authoring, reuse, modification, comprehension, and debugging. In some aspects, LLM assistance resembles a highly intelligent and flexible compiler, or a partner in pair programming, or a seamless search-and-reuse feature. Yet in other aspects, LLM-assisted programming has a flavour all of its own, which presents new challenges and opportunities for human-centric programming research. Moreover, there are even greater challenges in helping non-expert end users benefit from such tools.
