One personal pet peeve I have is using obscure (and in this case, non-Google-able) acronyms. Its easy to just give the full name once, then use the acronym after.
The first two hits I get are for Gnu GCC and the Accenture article explaining what a GCC is.
The AI Summary box at the top of the page does have Global Capability Center, but it's far enough down that you have to expand the summary box to see that meaning.
