"Vibe Coding" seems like magic at first but starts falling apart realllll quick at a certain complexity level or if you want to make changes to existing code. If you don't keep an eye on your architecture, you will end up with a bowl of untangleable spaghetti code and some comically terrible engineering choices. That said, agentic coding in the right hands with well defined tasks can have you outputting days / weeks of work in one session; it's not every task, it's not every session, but if you can drive the "idiot savant" in the right direction it's truly an awe-striking and almost alien process to behold.

I've just recently set off time to have a few extended coding sessions, and the results are all over the place.
Guided in a good way for well defined tasks, it has saved me days if not weeks. Given more vague, or perhaps unreasonable tasks, it will quickly devolve into just delivering something, anything, no matter how "obviously" wrong it is.
