I think the risk that companies build their own systems of record - ERP, ITSM, CRM etc - is incredibly low Companies are not stupid. They have no competence here, the stakes are massively high, and regardless of how easy it is, they would still have maintain and optimize it, which is, ultimately, a distraction from their actual business. Same reason AWS, Azure and GCP are such incredible businesses I genuinely think the people who believe this have either never worked in a real business or simply live in spreadsheets with no understand of how enterprise software is bought and sold I do, however, think the risk of the legacy SaaS providers being beaten by AI-native competitors from below is much higher Figma ate Adobe’s lunch because collaboration was native to the cloud and Adobe couldn’t adapt. That’s the sort of risk that should be keep these legacy systems of record up at night, not people vibe-coding a replacement.
