## Summary

Gergely Orosz argues that waterfall planning failed because implementation was slow and plans went stale before delivery. He suggests that AI, which makes implementation roughly 100x faster or more, could make Big Upfront Planning viable again.

Hear me out:

We hated "waterfall" because after Big Upfront Planning, implementation took FOREVER, and by the time we were done, the plan was out of date

But with AI, implementation is rapid (100x faster, or more, than before)

So Big Upfront Planning can now make sense?
