I have read a fair bit recently about companies decomissioning/migrating their mainframe, in an attempt to make their workplaces more "technological".

I would like to hear others opinions about what they think that future of Mainframes is. Personally, I am of the opinion that if it aint broken, dont try and fix it. But then again, some companies Mainframes are 20+ y.o and may need an overhaul, which when you perform a cost/benefit analysis (not that I have, or know how) the decommissioning/migration option may prove to be the more financially viable option.

What do others think about the future of Mainframes?
