This reminds me of the arguments people used to start with me (far too) many years ago about mainframes and COBOL. "Mainframes are obsolete. They're on there way out." "Sell your stock in any company who is still using a mainframe." My retort was always the same: there are many business-critical applications mainframes run well at very large companies, and they are everywhere. It will take many decades for that to change, if they choose to change at all. And the cost to change over those apps will be far too large for many given the limited benefits and IT as a cost center. Also, IBM has too much to lose if they let the mainframe business die. They won't. They will keep improving and encouraging the mainframe ecosystem. (At the time, I acknowledge I didn't see Y2K as being a future issue that would provide a burning platform that changed the industry dramatically.) So many people walked away from those conversations shaking their heads and saying I was crazy under their breath. 20 years later, the memory still brings a smile to my face. - a proud PHP coder
