From hours to usage
For as long as we can remember, professional service providers have sold time. Law firms, consultancies, and accountants bill by the hour. Banks take a percentage of the assets a banker manages on your behalf. Each puts a price on human effort.
AI takes the effort out of the equation, and customers can feel it. They know lawyers are using AI, consultants are using LLMs, and banks are running agents behind the scenes.
Worse still, customers now self-serve, letting smart tools compare services. That’s how pricing follows behavior. People are moving away from billing by the hour toward paying for outcomes.
In its 2025 State of the US Legal Market Report, the Thomson Reuters Institute states that the billable hour, “may be long past its expiration date.”
And yet the human element is back in demand. We know this because Vivino, a popular wine app based in Denmark, has already run the experiment. Point your phone at a wine label, and it instantly gives the producer’s name, the region, the vintage, the average price, and a rating.
The app has been downloaded more than 70 million times. Co-founder Heini Zachariassen said Vivino processes 100,000 ratings a day, while industry bibles such as Wine Spectator and Robert Parker might rate 20,000 wines a year.
A 2024 study in the Journal of Wine Economics found that crowd ratings broadly align with those of professional critics.
With a single invention, the knowledge a sommelier accrues over a decade became a free resource in your pocket. Surely that was the end of the sommelier? Far from it.
Since the app launched in 2010, the sommelier’s role has become celebrated. The 2012 documentary Somm turned the Master Sommelier exam into a spectacle and made somms, in Decanter’s words: “The wine counterpart to celebrity chefs.”
In July 2025, with apps everywhere and chatbots also responding to wine inquiries, the Court of Master Sommeliers, Americas, passed the largest class of advanced sommeliers in its history.
The sommelier’s scarcity was knowledge, and the app erased it. But the key ingredient was never raw data; it was the person serving the table who could read the room. Who’s paying? Are they worried about looking cheap? What’s the purpose of the dinner?
It’s the sommelier’s responsibility to select the right bottle for the right occasion at the right price.
