Here's an article. Basically if your trading stocks no. If you are trading different instruments or want interaction with the money folks (connections) yes. https://financetracked.com/bloomberg-terminal

From it: "Bonds and Fixed Income: It provides the best data for interest rates and debt markets. Global Economics: It easily connects data from different countries, such as currency rates and government debt. The Chat Room: The messaging system is the industry standard. If you want to talk to the biggest players in the market, you often need to be on Bloomberg."

Bloomberg Terminal costs ~$24K per user per year, so the fact that people are paying for it implies it offers at least that much value. As mentioned elsewhere in the thread, most of that value lies in the data sources.
