Lol, you think IBM post false numbers? You’re an idiot.

Thanks Bill. Don't take my word for it. There's a video and presentation that describes the banking architecture I mentioned https://www.confluent.io/kafka-summit-sf18/kafka-in-the-enterprise/. That's the tip of the iceberg. I can spend all day posting more links to other banks with the same event driven architectures. The mainframe is critical to their core banking system but it's just a cog in the wheel. I'm not anti-mainframe. I work for a mainframe ISV and I hope to retire still working on the mainframe. When you say all banks are you including neobanks and fintechs which have exploded in recent years and disrupted the banking industry. I moved my banking to a mobile app only neobank ages ago and have never looked back. I still get a bank card and pay no transaction fees. I enjoy the same regulations and guarantees that I would get from a traditional retail bank. > 9 Mainframe Statistics That May Surprise You - Precisely > > | > | > | > | | | > > | > > | > | > | | > 9 Mainframe Statistics That May Surprise You - Precisely > > How important is the mainframe today?
