Something shifted this week

Brief

Hiten Shah’s newsletter is a concise roundup of readings that frame February 2026 as a moment when AI moved from abstract excitement to tangible shifts in work, product strategy, and behavior. The throughline is that AI is changing not just tooling but organizational roles: people are becoming reviewers of machine-generated work, non-engineers such as finance staff can increasingly build or automate through coding assistants like Claude Code, and founders need to revisit assumptions about defensibility as switching costs fall. Shah also emphasizes practical operating questions, especially pricing and monetization, by pointing readers to Bessemer’s AI pricing playbook and to the distinction between competitors validating a market versus customers validating a product. The most substantive cautionary notes are about AI’s limits and externalities: models remain “yes machines” that can confidently generate bad code, “taste” remains human, Reuters’ reporting on AI in surgery grounds the debate in real outcomes rather than theory, and “cognitive debt” offers a useful management metaphor for degraded team judgment.

Why it matters

Hiten Shah’s 2026-02-17 Product Habits newsletter argues that the AI conversation shifted from experimentation to operational and business-model consequences.

Key details

  • Shah highlights recursive self-improvement and the rise of human “reviewer” work as signs that AI systems are moving from novelty toward workflows where people increasingly supervise model output rather than produce first drafts themselves.
  • On business strategy, he points to CJ Roth’s argument that software moats based on switching costs are eroding, and pairs that with Bessemer’s AI pricing playbook as a practical guide for founders rethinking monetization under faster product commoditization.
  • On adoption patterns, the newsletter says finance professionals are emerging as notable AI power users via tools like Claude Code, suggesting coding leverage is spreading beyond engineers and changing who inside a company can ship quickly.
  • Shah flags two risk-and-management frames worth watching: Reuters’ reporting on real-world AI use in surgery as a check against hype, and “cognitive debt” as an analogy to technical debt for how teams accumulate flawed assumptions and thinking patterns over time.
  • The piece is mostly a curated link roundup rather than original reporting, with additional lighter links on Sega’s slot-machine origins and a golf-course-based framework for constraint-driven design.

Software moats, AI surgery, Sega's origin story, and why competitors aren't validating anything.

In the spirit of experimentation after 11+ years of writing weekly emails with links, I'm trying a slightly different newsletter style that feels more conversational and natural.

Love it or hate it, either way please hit reply and tell me what you think. We're in this together...

The moment we're in

Recursive self-improvement was science fiction a year ago. Zvi documents where it stands now. Read this one slowly. The founder in this piece noticed something changing in real time and had the clarity to write it down. He's right. You became a reviewer and you did not sign up for it.

What it means for your business

Software moats were always about switching costs. CJ Roth makes the case that those costs are collapsing faster than most founders realize. Every company with a "software advantage" needs to re-examine what that actually means. If you're trying to figure out pricing and monetization in this environment, Bessemer's AI pricing playbook is one of the more useful things I've read. Dense in the right way. Competitors confirm the market. Customers confirm the product. Most founders treat those as the same thing. This post lays it out cleanly.

On the ground right now

Finance people are becoming some of the most interesting AI power users. This Every piece on Claude Code explains why. Coding became optional. That changes who gets to move fast. People are leaving parties early to check on their agents. That's the punchline of Nikunj's piece on token anxiety, but there's a real point underneath it about what happens to behavior when background processes take on weight. AI is a yes machine. Ask for bad code, you get it. Bicameral mapped it out.

What AI still can't give you

Taste. That's the whole argument. Short piece, worth the five minutes.

Two things worth paying close attention to

Reuters did actual reporting on AI in surgery. Not theoretical risk. Real outcomes. Read it before the narrative gets too far ahead of the facts. Cognitive debt is a frame I hadn't encountered before. Technical debt is what happens when code accumulates problems over time. Cognitive debt is the same thing happening in your team's thinking. The framing is useful.

One for fun

Sega started as a slot machine company. They sold to US military bases overseas, got banned for bribery, and somehow ended up building some of the most iconic games in history. The full origin story is genuinely strange and worth it.

Bonus link (couldn't help it)

Someone spent a month analyzing elite golf courses and built a strategic design framework out of what they found. The framework itself is interesting as a way to think about constraint-based design. Useful well outside the fairway.

Hit reply. Tell me what you think of this format.
