It's pretty plain to see IBM afraid of loosing vendor lock-in, but running a software solution designed for an open or distributed platform shouldn't be that big of a threat, right?

All their selling points for z series are the insane hardware performance, redundancy, and tuning.

Isn't it unlikely you're going to get that on some virtual or abstracted mainframe platform?

If I was one of the businesses that's been paying the fortune keeping IBM mainframe alive, I'd stay on it. They measure profits in the billions and saving some money going away from IBM and risking loosing countless dollars per minute seems like a risk...

Oh wait, I forgot, all American Corps are currently (since the 80s-ish), worthless greedy fucks solely focused on short term profit and stock price regardless of long term consequences. Maybe they should save some money on one of the things that's helps make them billions...I bet that golden goose tastes amazing

since the 80s

Do you wanna know who sold the time-punch machines for the concentration camps to the Nazis?

Nazi Germany was IBM's second largest customer after the USA.

Yeah, damn, I always forget about that...just like they want...
