Here is what chatgpt thinks about it's threat to Google:

Will chatgpt erode google's advertising revenue

It is unlikely that ChatGPT, or any other single product or company, will have a significant impact on Google's advertising revenue. Google is a large and financially successful company that generates a significant portion of its revenue from advertising. The company's advertising business is diverse and multifaceted, and it is unlikely that a single product or service, such as ChatGPT, would be able to significantly disrupt or erode Google's advertising revenue.

ChatGPT is a chatbot that uses natural language processing and machine learning techniques to generate human-like responses to text input. It is not a standalone product or company, but rather a feature of the OpenAI language model GPT-3 (Generative Pre-trained Transformer 3). While GPT-3 is a powerful tool that can be used for a variety of purposes, including natural language processing and generation, it is not directly related to Google's advertising business.

It's also worth noting that the advertising industry is constantly evolving, and Google is well-positioned to adapt and respond to changes in the market. The company has a strong track record of innovation and a diverse portfolio of products and services that help it maintain a strong presence in the advertising industry.
