Plenty of kiddie comments here today. Meanwhile, the adult world (ie. the stuff that keeps money in circulation plus some others) runs on mainframes. And probably will for quite some time to come.
Fun Fact: back in the 80's IBM were considering a new mainframe line (Summit, IIRC), until someone pointed out that their existing customers then probably had some cumulative 3 Trillion dollars worth of investment in their current, run the buisiness on, software and it was really asking a lot of them to rewrite all that just so they might invest in something new and different. Thus the new z14 will happily run stuff written back in the 60's if that's what you want. And you would be surprised just how much of that stuff is still running and doing the job it was originally written for. You idiots probably think that you would sensibly replace a bulk ore carrier with a fleet of wee boats, because they are cheaper or something.
Meanwhile tonight, the money in your bank account will continue to be reconciled, mainly, by a big box with zSystems embossed on the side. Flame away if you want; you are not going to persuade a good proportion of the fortune 500 to move their core systems to x86 and #NET or similar real soon now (let alone abandon their 5 9's reliablilty).
