A grocery store at Bayview Village, an upscale mall in Toronto, uses this system to stop cart travel outside the grocery store parking garage. Mall management considers carts trashy and that they otherwise bring down the appearance of the mall. This was one of the conditions when the store opened in 2005. Their cart policy may have changed 20 years since.
Bad actors will now be working to scam users' LLMs rather than the users themselves. You can use more LLMs to monitor the LLMs and try and protect them, but it's turtles all the way down.
The difference: when someone loses their $$$, they're not a fool for falling for some Nigerian Prince wire scam themselves, they're just a fool for using your browser.
Or am I missing something?
