I'm just horrible with acronyms because I work in IT and the health industry, previous the security industry. They all have acronyms and the same acronyms. So they all mean different things to different people. Acronyms are a lazy person writing and you have to be "in the know" to know what they stand for. 100 years from now, no one will be able to understand them.

"communicate so that everything you say can be understood 100 years from now" seems like a terrible standard to hold conversation to.

What is "IT", by the way?

Information Technology.
