Ever since we did Episode 7 -Why are Mainframes Still Around? we were left with the realization that really all the podcast involved was a bunch of non-mainframe programmers making speculations about why the dinosaurs didn't become extinct in our world?
Granted, I did a bit due dillegence prior to Episode 7 via StackOverflow to get others opinions on the matter but still, my journalistic spidey senses tingled at the fact Episode 7 was a one-sided debate for the most part.
To remedy this, a friend put us in touch with Mainframe Consultant and Author: Craig Mullins. It was an eye opener of a podcast, Mainframes truly haven't lost their "super computer" moniker even in today's advances with cloud computing.
Around the time I was arranging this interview I thought to get in touch with a previous colleague named Glen Sepke. We went to grab a beer and I told him my aforementioned feeling about Episode 7. He agreed it was too one-sided. So I offered to have him on the podcast so it wasn't just us against Craig Mullins 
So Why Do Mainframes Still Exist? As "modern developers" we really need to ask these types of questions and get credible answers. Otherwise, people tend to alienate that which they don't know. It's why developers (and, yes, I was in this camp), snicker at the term "COBOL" and "Mainframe". Its because we truly don't understand them, and thus a lot of FUD is created. Mainframes are perhaps becoming even more relevant now that they can run Java and talk to the outside world via Web Services.
So give this episode a listen and open your mind to allowing Mainframes their rightful place in today's modern computing arena.
Enjoy!
