The head of Germany's cartel office, Andreas Mundt, has cautioned that artificial intelligence (AI) could strengthen the market power of Big Tech companies, raising concerns about potential anti-competitive behavior. He highlighted the advantage these tech giants possess due to their vast user data, which can give them an edge in AI applications like smart homes, web search, and online advertising. Companies like Google and Microsoft are investing heavily in AI, leading to regulatory efforts worldwide to establish rules for AI use. Mundt emphasized the need for competition in the AI sector and the importance of preventing dominance by large corporations.
