AI is only useful for really big companies with enormous amounts of customer data.

This statement is false. While large companies with extensive data can certainly benefit from AI, its utility extends to businesses of all sizes. Small and medium-sized enterprises (SMEs) can leverage AI tools for tasks like automating customer service with chatbots, personalizing marketing campaigns, analyzing website traffic, optimizing ad spend, and generating content. Many AI solutions are now accessible through cloud-based platforms, requiring less upfront investment and technical expertise, making them viable for businesses with limited resources. Therefore, AI is not exclusively for "really big companies" but offers valuable applications across the entire business spectrum.
