Also, with an LLM you can tell it to throw away everything and start over whenever you want.

When you do this with an outsourced team, it can happen at most once per sprint, and with significant pushback, because there's a desire for them to get paid for their deliverable even if it's not what you wanted or suffers some other fundamental flaw.

Yep, just these past two weeks. I tried to reuse an implementation I had used for another project, it took me a day to modify it (with Codex), I tried it out and it worked fine with a few hundred documents.

Then I tried to push through 50000 documents, it crashed and burned like I suspected. It took one day to go from my second more complicated but more scalable spec where I didn’t depend on an AWS managed service to working scalable code.

It would have taken me at least a week to do it myself
