A single mainframe can handle workloads that would take dozens of x86 cloud servers, with nine nines of uptime. If you can afford it it pays for itself in terms of reliability and scalability.

That may be true but the dozens of x86 servers are cheaper and easier to use.
Sometimes quality of service matters more than cost.
If the consumer segment started to develop a sense that their payment cards were glitchy or unreliable, our economy could suffer real consequences. Error free, secure, instant payment experiences are essential. Go visit a local grocery store and measure how long it takes to authorize a transaction each time a card is presented to the terminal. Pay special attention to how fast the Visa and American Express networks are. At my local Kroger the terminal and network setup is so fast that you can use the chip reader almost like a mag stripe reader.
