I have been recently experimenting with Antigravity and writing a react app. I too didn't know how to start the server or what is "npm run dev". I consider myself fairly technical so I caught up as I went along.

While using the vibe coding tools it became clear to me that this is not something to be used by folks who are not technically inclined. Because at some point they might need to learn about context, tokens etc.

I mean this guy had a single window, 10k lines of code and just kept burning tokens for simplest, vague prompts. This whole issue might be made possible due to Antigravity free tokens. On Cursor the model might have just stopped and asked to fed with more money to start working again -- and then deleting all the files.
