I only know one person who voluntarily devoted their career to COBOL. He was paid quite well until he retired from HECO. When he left, they had no choice but to migrate to a less obscure coding language. That was in 2013.
I actually am fluent in 20 or so computer languages.
I have a BS degree in computer science.
I know how to design a computer language.
One of my senior projects was to create a language,
write a compiler for it, and let other people use it.
COBOL was not, is not obscure.
What surprises me is why people find COBOL
hard to understand.
But then again I read code like you read this comment.
Full disclosure;
Retired Boeing real time software engineer,
that mainly designed power supplies for airplanes,
(Mine worked and didn't burn up)
managed multi million dollar projects,
and had to hide the fact I'm a life time NRA
member.
If you can't multi task, you are going to be history
in today's world.
Want me to design and build you a robot that will hunt
down cops parked and waiting to give you a speeding ticket?
It is easier than you think.
Aloha and stay healthy.
