evidence: Elon Musk took to Twitter to talk about his new artificial intelligence company, xAI, outlining a goal of building a super-intelligent AI that could help solve complex scientific and math questions and "understand" the universe. [...] Musk has been outspoken about AI for years, famously saying in 2014 that inventing super-intelligent computers would be like "summoning the demon" and could create an existential threat to humanity. He helped found ChatGPT-maker OpenAI in 2015 but left the company in 2018 after disagreements with its other leaders. Over the past few months, he has complained about OpenAI and other AI companies scraping Twitter data to help train their bots. Tesla, the publicly traded electric-vehicle company that Musk is the primary owner of, has a robust AI team who have already worked for years on giving the cars self-driving capabilities. Musk has said his new AI venture will work closely with both Twitter and Tesla. Investors have criticized Musk for using Tesla resources to help his other ventures, especially Twitter.
