this always seemed TOO happy to mean "joy" to me!

if you search for images of joy, you get a LOT of Inside Out

and also a lot of lens flare

like, a lot

so much

on and on

ChatGPT will give you lens flares, too. Why lens flares, I asked. "Lens flares are often associated with joy because they evoke the brightness and energy of sunlight, which is commonly linked to positive emotions like warmth, happiness, and freedom. Visually, lens flares can create a sense of liveliness and motion in an image, enhancing the dynamic quality of the scene. When used in moments that feature bright sunlight, the effect can highlight the carefree, radiant feeling often associated with joyful experiences, like playing outdoors, celebrations, or simply basking in a beautiful day."

so many misguided thoughts on this! - will end poverty! - will end corruption! - will create world peace!

not just "money games for rich people" MoneyGram, UN, etc. Actual people, real use-cases. If "programmable money" is the argument that makes sense of blockchain, then it helps to have real money in the system.
