Why we picked it
This is the essay to read when you want to know whether a trend can carry a real company or is just a feature riding on someone else's model. Casado and Bornstein show why AI economics often look more like a services business than clean SaaS: lower margins, real infrastructure and human-in-the-loop costs, and moats that are shallower than the hype suggests. It is from 2020, but the core question (where does durable value actually accrue) is exactly the one to ask about any new AI wave.

- AI companies often run at 50 to 60 percent gross margins, not the 60 to 80 percent of classic SaaS, because compute and human review are real recurring costs.
- Model access is commoditizing, so defensibility comes from owned data, a narrow workflow, and real switching cost, not from the model itself.
- Before betting on a trend, ask whether it supports a standalone business or is a feature a bigger platform will absorb.

Why we picked it
This is written for the person deciding whether an AI idea is real, not for the engineer building it, so it stays in plain language a non-technical founder can act on. It names the exact red flags to distrust (jargon with no specifics, a founder who cannot point to a paying customer, a product that is just a thin layer on someone else's model) and the signals that actually hold up (owned data, a narrow real problem, real domain expertise). Treat it as a checklist for pressure-testing a trend, not a verdict on any one company.

- "We added AI" is not a business. Ask what data the startup owns and what specific, expensive problem it removes for a real buyer.
- The signal that a trend is real is willingness to pay and fast iteration on real user feedback, not demo polish or a slick pitch.
- Domain depth is the durable edge. A team that deeply understands one industry can defend a position that a generic wrapper cannot.
