The article argues that while AI/LLMs have dramatically reduced software development costs, they haven't eliminated them—creating a critical 'zone of viability' where purchasing specialized software remains more economical than building internally, even with AI assistance. For IT leaders, this means the buy-vs-build calculus has fundamentally shifted: high-value SaaS tools (like Salesforce at $25k/mo) now justify internal rebuilds, while mid-tier tools (like Jira at $400/mo) still favor purchasing due to hidden maintenance costs that LLMs cannot eliminate. Organizations must recalibrate their software strategy by analyzing true total cost of ownership, including the often-underestimated ongoing human oversight required for LLM-built systems.
