Summary
Building a software business in the age of AI presents challenges, as products can be quickly replaced by internal packages created by large language models (LLMs). The concept of a "minimum viable unit" of saleable software is proposed as a strategy to navigate this landscape.
Key Takeaways
- The introduction of LLMs has significantly reduced the cost of building software, but it has not eliminated the need for human oversight and ongoing maintenance.
- A custom internal task tracker built using LLMs may still require substantial time and resources for initial development and continuous refinement, making it a complex project.
- The financial comparison between using a commercial software solution and building an internal tool with LLM assistance reveals that the latter may not be cost-effective in the long run, especially considering the labor costs involved.
- The shift in software development dynamics due to LLMs has changed the traditional buy vs. build calculus, allowing for more feasible internal software solutions.

Positives
- The cost to build software has significantly decreased, enabling more individuals to pursue side projects that were previously unfeasible, which could lead to greater innovation.
- AI tools have made it easier for developers to push through obstacles, allowing for quicker iterations and the ability to create throwaway versions of projects.
- Creating working code is becoming cheaper with AI, which can lower barriers for entry into software development and spur creativity and experimentation.
Concerns
- Despite the lower costs, the effort and motivation required to maintain software projects still pose significant challenges, often leading to stalled progress.
- The risk of isolated solutions in the community could lead to incoherent software that lacks vision, which is a concern for investors and developers alike.
- Creating effective specifications for software remains a complex task, as AI struggles to identify and rectify usability issues without user feedback.
