Food is worth a lot more than that. If the alternative was starvation, we would pay approximately all the money for food. By that metric food is worth more than $100T. The difference between $100T and $10T is called the consumer surplus, one of the largest benefits of a free market economy.
AI might eventually provide $26T worth of value, but if it captures anywhere close to that amount of revenue that'll indicate a failure of the free market economy. Competition and open source will have failed and the oligarchy has won.
(Either that, or inflation will have made $26T a relatively smaller number).
