Looks like it's already been pointed out. We’re not applying AI to these systems — IBM is already pursuing those initiatives (https://research.ibm.com/blog/spyre-for-z).

Our focus is different: we’re using AI to understand these 40+ year-old black box systems and capture the knowledge of the SMEs who built and maintain them before they retire. There simply aren’t enough engineers left who can fully understand or maintain these systems, let alone modernize them.

The COBOL talent shortage has already been a challenge for many decades now, and it’s only becoming more severe.
