An anonymous reader quotes a report from the Wall Street Journal: A battle of insults and threats has broken out between the tech world and Wall Street. What's got everyone so worked up? The same thing that starts most fights: business software. A series of social-media posts went viral in recent days with claims that AI has created a worthy -- and way cheaper -- alternative to the Bloomberg terminal, a computer system that is like oxygen to professional investors. Now "Bloomberg is cooked," some posters argued as they heralded the arrival of a newly released AI tool from startup Perplexity. [...] The finance bros who worship at the altar of Bloomberg have declared war on the tech evangelists who have put all their faith in AI. To suggest that the terminal is replaceable is "laughable," said Jason Lemire, who jumped into the conversation on LinkedIn. (Ironically or not, his post also included an AI-generated image of churchgoers praying to the Bloomberg terminal). "It seems quite obvious to me that those propagating that post are either just looking for easy engagement and/or have never worked in a serious financial institution," he wrote. [...] Morgan Linton, the co-founder and CTO of AI startup Bold Metrics and an avid Perplexity Computer user, said it's rare for a single AI prompt to generate anything close to what Bloomberg does. That said, he added that tools like this can lay "a really good foundation for a financial application. And that really has not been possible before." Others aren't so sure. Michael Terry, an institutional investment manager who used the terminal for more than 30 years, said he used a prompt circulating online to try to vibe code a Bloomberg replica on Anthropic's Claude. "It was laughable at best, horrific at worst," he said. Shevelenko acknowledged there are some aspects of the terminal that can't be replicated with vibe coding, including some of Bloomberg's proprietary data inputs. The live chat network, which includes 350,000 financial professionals in 184 countries, would also be hard to re-create, as well as the terminal's data security, reliability and robust support system. "I love Bloomberg. And I know most people that use Bloomberg are very, very loyal and extremely happy," said Lemire. His message to the techies? "There's nothing that you can vibe code in a weekend or even like over the course of a year that's going to come anywhere close."Read more of this story at Slashdot.
