Any business gathering, in any language is filled with hollow - English - buzzwords. Part of this is to blame on executives who want to show of by using "fancy" words. But a big part I think is simply people learning the new universal language in business: "Business English".
Business English is spoken by non-native English speakers, unlike proper English, it has a very small vocabulary and people are in need of finding words/verbs/concepts to express common things. You hear others speak Business English, you read documents online in Business English, you see YouTube videos in Business English. And hey you learn, this is how you communicate.
Business language and culture are also deeply linked I think. Overhearing a conference room discussion as an outsider might soon completely ridiculous in terms of buzzword use, but to everyone on the inside, these are just verbal shortcuts that sound perfectly normal, and everyone knows exactly what everyone means.
The challenge is to be aware of this when you start talking to people outside of this inner circle.
