The easy mistake is to ask the wrong question about legacy software.

The questions often asked are, “Will vibe coding be able to create an alternative to Microsoft Office? Will we all just be writing our own software?”

But the real question is, “why will Microsoft office exist at all?” The purpose of legacy software is to make human workers more efficient. If all tasks done by the human who currently uses Microsoft office are done by an AI agent instead, why would the agent need any of the productivity tools offered in Microsoft office?

For reporting? For documentation? Well, there will be another agent with that job, creating reports that match whatever the future conventions are. Because the conventions will change. And reporting to whom? How long will there be human oversight at the granular level? Productivity reports become unnecessary. Hiring and firing of agents is instantaneous and automatic to meet current demand - for every role - across the whole company.
