Do you think PayPal, Ebay or TradeMe use COBOL code to manage their
financial transactions? Of course not.

 How many government agencies, financial institution and so forth do you
think DON NOT have reams of legacy COBOL?
 

I suspect PayPal and Ebay actually do still use COBOL somewhere
The investment represented by 5-10 man  years of COBOL back in 1975 is a lot more than the machine to run it on today, and the glue software to integrate it into whatever software muddle companies use today.
My brush with financial software suggest that it is (or was 15 -20 years aqo) run on Oracle databases, by and in Oracle aligned software data centres. In short the code development and the data is outsourced to a big secure data centre
Oracle had a version of COBOL (PRO COBOL) that is able to call SQL statements.
I think it is still supported.
They also have a FORTRAN that can interface to it. What better place to put gigabytes of scientific data than an Oracle database?
And scientists still use FORTRAN
Now as far as new code is concerned, COBOL is still being written. But my nephew who writes banking software in Australia says he uses Java mostly.
A friend who does that uses C++
I've written database based software in PHP, and C. As a web application.
"about 240 billion lines of COBOL are in use today, and about 5 billion lines of COBOL code are written each year, claims IBM"
...a random google found.
There are huge FORTRAN libraries around that have taken years to write.
COBOL and FORTRAN are not hard languages to learn, especially for non computer nerds. And they work and are well supported.
Why NOT carry on using them?
