I think this is only surprising for some people because the tech growth-adoption mentality of the last couple of decades needed and benefited from UI that became increasingly optimized for 'ease of use', for 'everyone', for universality. But bloomberg terminals do not need to be massively adopted. You don't need more (less specialized) terminal operators. That market/user-base didn't need to grow as much as excel users, browser user or CRM users. As we reach peak digital tools/process adoptions I expect more and more specialized tools that don't try to be 'easy to use' first.
