It is the same evolution you see in other industries. Auto mechanics
constantly complain about how the newer generation is 'dumber' for not
knowing the beauty of a vehicle that the mechanic had when they were
in their teens. [Of course they also rail on the fact that their
grandparents car was a complete junk that was too simple to work.]
Most of the tools we had 30 years ago in computers are like working on
a Model T era vehicle. They allowed for a lot of configuration choices
and fine tuning but they also were limited vastly in other ways. You
can't run a fleet of 1000 Model TT trucks made in 1923 as well as you
could 1000 1933 trucks. You ended up losing some of the knowledge of
hand-crafting your own gears but you got the ability to go faster,
carry heavier loads and better gas mileage without working as hard at
getting a mile out of a quart.

The transmissions of the 1933 were considered 'automatic' compared to
some 1912 vehicles.. even if you had a clutch because you no longer
had to get out and turn something to make it go in reverse. The
'truly' automatic transmissions of the 1950's were horrible and it
wasn't until the 1970's where they became 'liveable'. Today trying to
find a real stick shift is almost impossible as you find out that the
most are really talking to a computer which does the shifting when it
decides is optimal.

As that happens the place where a programmer makes changes goes higher
and higher. They no longer see a system by itself but see 10,000 nodes
sitting in some cloud. They really could care less if 10% of them drop
off because there is a tool which is going ot bring 1000 back online
when that happens. However they may still be worrying about making a
change 'low' level to them. It is just light years above where those
of us with only 10 or a 100 systems can dream about.
