Mainframe and AI: The Sustainable Choice

In this insightful and forward-thinking session from the Artificial Unintelligence Conference, Rosalind Radcliffe, IBM CTO for the Z Ecosystem, explores what it truly means to build sustainable AI systems — not just faster ones.

Radcliffe challenges the industry’s obsession with scale and performance, arguing that innovation doesn’t always mean more consumption. From hybrid architectures to smarter system design, she shows how sustainability must evolve from a peripheral goal into a core design principle that informs every layer of enterprise technology.

Key ideas explored:
• Why sustainability in AI is as much a mindset as a technical challenge
• How thoughtful architecture choices reduce energy and resource demand
• The role of hybrid systems in balancing modernization with responsibility
• Why progress should focus on efficiency, not endless expansion
• How organizations can embed sustainability into their digital transformation strategy

This session reframes sustainability not as a constraint — but as a creative challenge that can drive smarter, more responsible innovation across industries.
