Sponsor Session Overview

Theme: What AI Can Write Shouldn't Be Written

Date: February 20, 2026, from 11:50 AM to 12:20 PM

Speaker: Yusuke Sugimori (CTO, Marui Unite)

The integration of AI in software development raises the potential for engineers to produce an unprecedented amount of code. While it might seem tempting to allow AI to handle all aspects of large-scale system implementation, the reality remains that human cognitive capacity is often the bottleneck. Therefore, successful in-house development teams must prioritize not only what AI is allowed to develop, but also what should be left out of its hands.

Sugimori believes it is essential for teams, particularly those undertaking significant legacy transformations, to strategically determine both what to develop and what to consciously omit as they deploy AI-driven solutions. He aims to share his insights on navigating these complexities during his presentation.
