Yeah I remember watching that and thinking oh I know a cool app idea. What if you just take a video of what food is in your kitchen and Chat GPT will create a recipe for you. I go to the docs and that was literally the example they gave.

I think the only place where plugins will make sense are for realtime things like booking travel or searching for sports/stock market/etc type information.

I have a home-spun version of ChatGPT that uses function calling to connect to my emails, calendar, and notes. This is really useful because I can say "Bob just emailed me to set up a call. Respond to Bob with some available times from my calendar."

That will be the real use case for plug ins.
