The focus is on downstream, but is upstream ready for this speed up?

The linked blog post draws comparisons to the industrial revolution however in the industrial revolution the speed up caused innovation upstream not downstream.

The first innovation was mechanical weaving. The bottleneck was then yarn. This was automated so the bottleneck became cotton production, which was then mechanised.

So perhaps the real bottleneck of being able to write code faster is upstream.

Can requirements of what to build keep up with pace to deliver it?
