I just calculated the spending on AI this year, which is about 1000 USD a year, and suddenly thought of the Engel coefficient.

Engel coefficient = Total food expenditure ÷ Total household income × 100%

The higher the Engel coefficient, the poorer the household.

In the future, as AI develops, the weight of the AI Engel coefficient will become popular. Conversely, the larger the AI Engel coefficient, the wealthier the household🧐
