Google's CEO announced that AI systems now generate over a quarter of new code for its products, a development that boosts productivity and efficiency. AI-generated code is reviewed and approved by human engineers, illustrating AI's growing role in software development. Google's use of AI reflects broader industry trends, with surveys showing high adoption rates among developers. AI tools like GitHub Copilot, using models from companies such as OpenAI and Google, have popularized AI-assisted coding. However, concerns persist about potential bugs and over-reliance on AI-generated software, as noted in a Stanford University study highlighting increased bugs in AI-assisted code.
