My Best Mainframe Tip for Long-Term Success: Keep Learning
 
Where I Started: I began my Mainframe journey as an application programmer, focused on helping a major public utility in Pennsylvania run their business.

What I Learned: Over time, I discovered that success in Mainframe wasn’t just about technology/skill — it involved collaboration, continuous learning, understanding legacy systems, and more. I expanded into a pre-sales role in the software vendor environment and this became even clearer as I progressed in my career.
 
My Best Tip: Here’s the tip I always share with others: Don’t feel you’re making the wrong career choice when you hear ‘the mainframe and COBOL are going away’. I’ve heard that argument often in my 48 year career. More recently we have read about AI displacing the mainframe and COBOL in 2026 (remember Mark Twain in his time mentioned “The reports of my death are greatly exaggerated”). If you don’t believe me, have a look at these visions from IBM leaders:

Continuously learn and grow in the IBM Z space. You’ll never run out of material nor out of career opportunities, and you’ll find a space where both old and new technologies combine to form valid solutions for businesses across all industries.

Remember: you don’t need to know everything. Seek not to know all the answers, but to understand the questions. Start where you are, stay curious, and lean into the community. Growth in this space is continuous — and incredibly rewarding.

I rest my case…)
