But millions discussions are needed and will always be needed?

"Create a copy of Amazon.com"

ok, how did you want to handle 3pl fulfilment and international red tape?

"No not that complicated, a minimal copy"

How minimal? How many servers should I provision? How vertically integrated should we get?

Etc.

I really want to see someone build an app of any value with minimal decisions made.

Amazon is not one app, its hundreds of them bundled in some giant monster.

You could easily replicate the store part of it minimally, at its core its just an index of products, a basket and checkout system. There are other parts that make up the whole thing of course.

There is a lot of room between no value and trillion dollar company

It would be great if LLM's did this (the relevant, and very pointed, follow-up questions). Instead, today they kind of just go "okay sure yeah here it is. here's as much of Amazon.com as I can code within my token budget. Good luck drawing the rest of the owl."
