> This has me wondering why the software world is so unpredictable in the first place… Also, why are we so inclined to think the physical world is so predictable?

Ignoring time spent designing, software's manufacturing time is essentially zero. Compare that with days/weeks for devices and years for vessels/structures. So because we're used to the latter timescale, the pace of software feels like watching a video at 100x speed.

If engineers could instantly and cheaply print each new version of the airplane or bridge they're tasked with building, they'd start looking a lot more like the software industry. When software doesn't have its rapid/free iteration superpower (as in the early days or in must-never-fail situations), it starts looking like traditional engineering.
