Slightly OT, but one thing I noticed further into the demo is how you were prompting.
Rather than saying “embed my projects in my portfolio site” you told it to “add an iframe with the src being the project url next to each project”. Similarly, instead of “make the projects look nice”, you told it to “use css transforms to …”
If I were a new developer starting today, it feels like I would hit a ceiling very quickly with tools like this. Basically it looks like a tool that can code for you if you are capable of writing the code yourself (given enough time). But questionably capable of writing code for you if you don’t know how to properly feed it leading information suggesting how to solve various problems/goals.
