SaaS in the Age of AI: The Great Software Overhang

Summary

The piece draws an analogy to the steam engine’s delayed economic impact: macro AI adoption is early, but something distinct is happening at the SaaS layer right now. The “software overhang” concept — visible in the intro but developed behind a paywall — points to accumulated software complexity, legacy tooling, and workflow lock-in that hasn’t yet been disrupted by AI-native alternatives. When that overhang clears (AI-native tools displace incumbent SaaS), the transition is likely to be fast because adoption of AI tools is compressing release cycles.

Implications

• Feeds the token economics competition thread: the SaaS overhang is the demand-side context for why subscription economics are under pressure — if AI-native tools can replicate SaaS functionality with lower per-seat cost, the incumbents’ pricing power erodes before their customer bases actually migrate.
• Relevant to enterprise deployment as battleground: the overhang clears through enterprise procurement, which is why every CLI agent vendor (Anthropic, OpenAI, GitHub) is racing for enterprise deals — the institutional switching cost is high, but once it tips, the replacement is durable.
• Background for Nate’s “Five Durable Layers”: distribution is the layer that holds SaaS incumbents in place longest (existing contracts, integrations, org habits); AI tools that win distribution before the overhang clears inherit those contracts rather than fighting for them.
