> except probably the finance users don't like random UI changes, lol

I have bad news for you, nobody who works with a system more than casually, likes random UI changes. NOBODY. Younger people are often more tolerant to these distractions, because they are often more curious. But when you have used a tool for some longer time, and suddenly it looks or behaves different, that erodes trust. That forces the user to turn of the mental autopilot and to proceed with care. Which A/B tests will report as increased engagement of the users. And there is our vicious cycle.

Note, how a scheduled update with release notes does the opposite. It increases trust, because it tells you what is going to happen and then it happens. (Hopefully)

The real reason to have bloomberg, other than data, is actually the chat.

OTC (things that don't trade on exchanges) markets are a lot closer to ebay or facebook marketplace than many realise, for example, e.g. you ask for a price, possibly haggle a bit, say you want it, behind-the-scenes people scurry off and actually make it happen.

When you first activate your terminal bloomberg send you an email congratulating you on joining "the exclusive club" (this is exaggerated, they want you to feel special, but there's truth to it).

As well as all that bloomberg is technically also still (iirc) one of the largest private computer networks.

Unfortunately possibly quite the opposite for many, although no first-hand experience.

lol this is probably most famous financial tool on the market. No wonder we have so many new software tools being created daily since some people don’t do basic market research.
