On: IBM mainframe beats other platforms for cost and performance

> high reliability through redundancy ... easy physical maintenance through hot-swappable components

I don't think hyperscalers will ever care about this. They have millions of servers. They can just take the whole server out of commission as soon as it fails a health check. This is a critical difference between the mainframe model and the modern cloud model.

Yup - look at the sleds in the opencompute project, or the rack product Oxide is working on. Whole servers swap about as easily as hot-swap SATA trays
