2026: THE YEAR OF CHURN

"Does it integrate with Salesforce?" was the question buyers asked for a decade. Now, they want to know if agents can drive your product, if your APIs are clean, and if there's an MCP connector. Buyers asking those questions are buyers running the math on whether to keep you. The math gets worse when a vendor they already pay adds a 60% version of what you do, because AI fills enough of the rest that cutting your $80K contract stops feeling like a tradeoff. Annual deals have hidden how often this is already happening.

SOFTWARE IS EATING THE WORLD (BUT ACTUALLY THIS TIME)

AI agents now execute the actual work as code loops rather than just mediating interfaces, converting human jobs into tool calls and verification steps. Agentic tasks burn orders of magnitude more tokens than chat because a single Claude Code bugfix can consume around 900k tokens, where almost all goes to context replay and tool output rather than visible code. METR data shows autonomous task horizons doubling every 131 days, jumping from 4 minutes on GPT-4 to roughly 12 hours on Claude Opus 4.6 and pushing OpenAI past 15B tokens per minute alongside Google's 50x YoY token growth.

A NEW TOKEN RULE FOR ENGINEERING LEADERSHIP

Chainguard now expects its engineering managers to be at the 50th percentile of token usage among their direct reports. Managers who use too few tokens lack the context needed to manage and move results forward. Managers who use too many tokens need to focus on increasing token usage amongst their teams. Right around the middle means that both managers and their teams understand what their tools can do.

THE FOUNDER'S GUIDE TO BLOGGING

Polished prose used to take effort. Now, any founder can produce a clean feature announcement in ten minutes, but most of them read like the same announcement. Swap your company name for a competitor's and read your last post again. If it still makes sense, you wrote a press release. Don't hand the model a feature spec and ask for a polished post. Hand it the customer ticket, the Slack argument, and the voicemail where you explain why this even matters.

THE BRAVE NEW WORLD OF AI MARKETS

It is naive to assume that the Total Addressable Market (TAM) for artificial intelligence will simply equal the current size of the global human labor market. This post proposes a new framework for sizing AI markets based on the classic economic equation of Price multiplied by Quantity (TAM = Human Labor TAM × Price Compression Factor × Volume Expansion Factor).

DIRECTION OVER SPEED

For most of software's history, you could fake productivity by shipping a lot. AI broke that cover. Prototypes are cheap, specs write themselves, and shipping looks the same whether you're building the right thing or the wrong one. Smaller teams of four or five, with the PM closer to the work, especially on AI features where "is this good" can't be answered by a metric. The model can build the thing for you. It still can't tell you why anyone should care.

SHIPPED ISN'T SOLVED

A customer asked for a feature on a call. The team built it, shipped it fast, and moved on. Nobody really used it. Speed only helps if you understand the problem before you start building. Look at your last five shipped features and count how many customers were still using each one a month later.

AI market gains currently favor vendors like Nvidia, while broader productivity benefits remain underpriced.
