Professions tend to have their own language. Academia, doctors, lawyers, politicians. You need to master the language in order to be part of the club. Once you are part of it, you filter the language and extract what it actually means.
Managers in corporations have such a language as well, it is called the presentation. The key messages are hidden in bullet points, consulting frameworks, and buzzwords. Junior managers learn the craft by spending hours creating the deck and iterating them, senior managers know how to read in between the lines and get to the issue that matters quickly (the 2nd part of the proposed budget on page 35).
We got rid of formal letters and replaced them with informal emails and messages. It is time make those presentations more to the point as well.
Part of the solution is more visual slides (imagers, less text). But the most important change is a cultural one: saying what we want to achieve in a short and to the point matter.
