Someone said that using a chat-only interface is like using CLI tools. It's even worse, I would add, because there is no autocomplete or man command to help you out. Most of us here probably get it, but my dad had a hard time getting a good answer from GPT when he first tried it, even with GPT-4 model.
Hence the need for specially trained people who can do the back-and-forth with humans to understand exactly what is required, then enter it (into the brittle prompt in this case) in a way that the computer would understand.
