They may panic, but they shouldn't. They can quickly pivot. GPT programs can be used off the shelf, but they can also use custom training. Every large org has a huge internal set of documents, plus a large external set of documents relevant to its work (research articles, media articles, domain relevant rules and regulations). They can train a GPT bot to their particular codebase. And that is now. Soon (I'd give it at most one year), we'll be able to train GPT bots to videos.
All this training does not happen by itself.
