I usually ask it to write me a nextjs app and deploy it to vercel. It gives me a few commands and files to plop in the right directories. E.g. `npx create-next-app foo; cd foo; ...; vercel --prod;`. Often I only make a couple changes then 5 mins later it can be deployed for free on vercel. Eg, it took me a couple mins to create a lil app to enable a user to drag/drop words of your sentence. I asked chatgpt (gpt-4) the following: "Write me a nextjs app (and deploy to vercel) that shows the sentence 'Anyone have any good examples or tutorials of specifically how to use ChatGPT for greenfield code development ?' but each word is draggable and re-arrangeable such that a user can drag any word to anywhere in the sentence. Add a randomize button too."

It's incredibly empowering to be able to easily spin up little proofs-of-concepts or bootstrapping larger projects. I think all the naysayers have not experienced its power yet.

I asked it to design and implement an entire software system. I just copy-pasted the output and it (almost) worked the first time.

(It ran out of context window and started forgetting the design; if I'd started each message with the design and class layout it would have probably worked the first time!)

Specifically I asked it for a design, then a main class, then for each of the other class files. (This process could probably be automated.)
