That link does not say that they are switching away from a system that requires armies of consultants to implement.
AFAICT, they are switching away from Jira (Atlassian/confluence products). Those are not ERP systems.
Once again, I must point out that the these sorts of assertions reveal that the person making the assertion has never been involved in an ERP rollout, neither a big one nor a small one.
And, again, I reiterate, the only threat is to small players in the market, who don't have a community to hire from. Because to become a big player, you need to gain traction as a small player, and if every small ERP system can be replaced with an AI generated system, non single one is ever going to gain traction (Why pay $10/user/month for a basic system when you can have AI generate that for a once of fee and some employee time?)
That said, plenty of banks still run on mainframes and use COBOL.
