The thing blocking level 8 isn't the difficulty of orchestration, it's the cost of validation. The quality of your software is a function of the amount of time you've spent validating it, and if you produce 100x more code in a given time frame, that code is going to get 1/100th as much validation, and your product will be lower quality as a result.

Spec driven development can reduce the amount of re-implementation that is required due to requirements errors, but we need faster validation cycles. I wrote a rant about this topic: https://sibylline.dev/articles/2026-01-27-stop-orchestrating...
