This is a good summary.
I'll add that many XD people (eXperience Design: people who try to make software easy and pleasant to use, and better meet business goals with that software) take one look at a Bloomberg Terminal and just about have a stroke. For them, it's a coarse tool from another age that must be "fixed".
However, that impression is from a first glance with no user research. Terminal users love the Bloomberg for the reasons listed above. AND any change to it brings financial risk. AND they make a lot of money using it. AND (please don't discount the human element here), some get off on their mastery of a complex tool that most of us wouldn't touch. Mastery is a powerful driver here, just as it is in gaming. 'this is a tool for experts. I'm one and you're not because you can't.'
The way the Bloomberg terminal might get replaced is by new people who don't come up in the ranks using it, but using an alternative when there's a workable one, or more likely by AI trading directly (God help us...).
