I mean, do you have any hobbies or does every cent you have go to food, rent, and savings, with no frivolities, not even a drink after work or food that isn't rice and beans? Some people play video games or painting or carpentry or what have you. Instead of spending money on alcohol or sports, some people with FAANG-level salaries choose to spend their entertainment budget on GenAI art projects. Not your cup of tea, totally fine, but I suspect your budget has something others could choose to find frivolous if someone wanted to nitpick.
