This is what Apple's Siri was meant to be. Apple bought Siri from SRI international (Siri = SRI), and when it was launched was meant to include ability to book restaurants etc (thereby bypassing search), but somehow those capabilities were never released and today Siri still can't even control the iPhone!
My hot take on ChatGPT plugins is a bit mixed - should be very powerful, and maybe significant revenue generator, but at same time doesn't seem in the least bit responsible. We barely understand ChatGPT itself, and now it's suddenly being given ability to perform arbitrary actions!
