Coming from the guy who said he does PayPal, Amazon, & Apple transactions and
doesn’t know those transactions are mainframe processed through a bank.
So what? The payments system is not running on a mainframe. Nor is the
mobile payments back-end and all the other infrastructure. Paypal are
moving to GCP

You seem to think I am bashing the mainframe, which I am not. I love the
mainframe. I work on it everyday and have done for 30+ years. But I have
a low tolerance for BS!

In what parallel universe did Amazon, Paypal run a mainframe? lala-land?
If I google "paypal technology stack" and I don't see a mainframe!
Mainframes are for running legacy applications written in COBOL, PL/I etc.
Paypal is written in Java, Scala, Python and recently replatformed to
Node.js - JavaScript!
