The next generation.
The lazy AI-era take is that agents will replace business software. The lazier take is that business software is fine and doesn't need to change. Neither view has spent enough time with an actual ERP implementation. Enterprise software is two things, not one — a data layer and an interface layer doing very different jobs. Only one of them is dying.
Business applications are a data layer: the general ledger, the bill of materials, the work order, the dispatch table, the opportunity pipeline, the case queue. The contract between business reality and software. The thing that has to be honest when an agent is wrong. A general ledger that hallucinates is not a feature; it's a lawsuit.
Business applications are also an interface layer: the screens, the workflows, the seventeen-tab forms, the way humans engage with the data. This is where most of the cost lives, where implementations burn twelve months, where users hate the product.
The agentic era takes the second one apart. The data layer holds. The interface layer dissolves, and the interface layer is 80% of what made enterprise software feel old. When people say "ERP is dying," what they mean is "the way I experience ERP is dying." They're right about that. What stays is the system of consistency. What changes is everything else. That's the next generation.
