He screenshotted a tweet and had Muse build a kids' bank with 3% weekly interest

After seeing another dad's idea, armandruiz screenshotted the tweet and asked Muse to build a family bank for his daughter: her allowance earns 3% weekly interest credited daily, with a growth chart, saving missions and a passbook ledger — and debt accrues interest too, teaching compound interest before she can spell it.

The original idea came from @joecarlsonshow, who set up an even more aggressive 7% weekly account for his kids with a scheduled task updating a daily ledger. His 9-year-old daughter now eagerly tracks her growing balance, while his 11-year-old son has already been through (and repaid) a debt cycle. ChatGPT calls it the weirdest thing he's ever set up.
