(typo for big but Freudian slip seems OK)
Once something becomes "complex" (i.e., too large to fit in a
single brain), it becomes difficult to understand the repercussions
of specific design decisions -- because you can't remember
EVERYTHING with which they interact.
Engineers design giant systrems - cars, airplanes, bridges, buildings
- with lots of parts, and nobody understands all the parts. And they
work first time.
In my lifetime (or of sufficiently common "lore"):
Hindenberg explosion
Tacoma Narrows Bridge collapse
Chernobyl reactor
Hyatt Regency walkway collapse
Apollo 1 fire
Apollo 13 O2 tank explosion
Space Shuttle Challenger
Space Shuttle Columbia
Skylab
Fukishima nuclear plant
Deepwater Horizon fire/"spill"
Doors falling out of airplanes
Titanic
BIG! chinese dam failure (no idea of name)
World Trade Center towers
Concorde
De Gaulle airport collapse
DC-10 engine falling off
Titan submersible implosion
All, obviously, software problems??

Bias? Or sheer Ignorance?
What fraction of airplanes or bridges or buildings collapse? Estimate
that in PPMs.
