Elon Musk told the Wall Street Journal CEO Council Summit in London that there is a need for an AI business to take on Google and Microsoft, and that Twitter could be part of his effort to create an AI business. Tesla has been using AI to improve its advanced driver assistance features. Musk said Twitter and Tesla could be partners in an AI company, similar to the relationship between Microsoft and OpenAI. Musk previously created an AI startup called X.AI on March 9. In addition, Musk said that Twitter's profitability is not strong, but positive cash flow will appear as soon as next month.
