There may be potentially be a cultural factor involved at
Fukushima, I don't remember specifically right now. I do 
recollect that cultural factors relating to "loss of face"(?)
have historically been a factor in *some* aircraft incidents, 
but can't bring specific ones to mind right now.

I do remember that as with many significant failures, the
Fukushima incident involved a whole string of engineering, 
management, and regulatory foulups over a number of years. 

If a significant proportion of those had been addressed, 
things might have turned out different. But too many weren't
addressed.

Further Fukushima-preventability reading includes:

In a different context, the chain of issues which caused 
the total loss of Air France Flight AF447 were also relatively
well known and understood on an individual basis. But they hadn't
been taken seriously enough by management, individually or
collectively. It's a surprisingly common situation when the 
probabilities are small and decreasing, but the impact if 
Something Bad does happen is high. Which is why some #
safety-conscious organisations encourage reporting "near
misses" as well as actual incidents. Statistics can lie,
but they can also inform.

Here's a recent AF447-prompted article about the impact of 
automation and the resultant decline of understanding and 
skill in modern cockpits:
https://hbr.org/2017/09/the-tragic-crash-of-flight-af447-shows-the-unlikely-but-catastrophic-consequences-of-automation 

Asiana Airlines Flight 214 was another incident where lack
of basic understanding, combined with failures in critical
cockpit communication, caused a problem, albeit not on the
scale of AF447.

AF447 and Asiana 214 are widely documented.


Now obviously a decline of understanding and skill 
couldn't have similar impact elsewhere, could it
Well, not until it becomes interesting to the media
anyway... 

The Raspberry Pi exists because one of the founders,
Eben Upton, who at the time was teaching at Cambridge 
University, got seriously concerned about the lack of
understanding shown by his undergraduate intake. This 
too is widely documented, e.g. Eben Upton's IET Young 
Professionals lecture from 2012 (around 45 minutes):

By all means keep things as simple as possible. But
someone somewhere needs to understand what's behind
the curtain, and more importantly the bean counters
need to trust these people, or Bad Things will be
on the way.

Have a lot of fun.
