Offloading your thinking, typing all the garbled thoughts in your head with respect to a problem in a prompt and getting a coherent, tailored solution in almost an instant. A superpowered crutch that helps you coast through tiring work.
That crutch soon transforms into dependence and before you know it you start saying things like "Once you vibe code, you don't look at the code".
Most of it is rather terrible, but a lot of the times it really doesn't matter. At least most of it scales better than Excel, and for the most part they can debug/fix their issues with more prompts. The stuff that turns out to matter eventually makes it to my team, and then it usually gets rewritten from scratch.
I think you underestimate how easy it is to get something to work well enough with AI.
