If you guessed the answer to "who said this?" was "the mayor of Mableton" then give yourself a pat on the back. The "tool" to which he referred is Artificial Intelligence. Using AI to provide broader, better services without an excess of money sponges.
Broadly speaking there are two types of AI: Large Language Models (LLMs) and Agentic AI. The former gives answers while the latter gets stuff done. Both can make very important contributions to open, transparent, democratic governance. Seems to be what they're doing over in Mableton.
With LLMs working on fully digitized records we, the people, can ask questions and get answers. Immediately. Accurately. Without spin. With proper configuration and training an LLM can properly redact sensitive information, far better than any money sponge, at a relative cost indistinguishable from zero. Suppose you wanted to know how many citations for code violations were issued in your neighborhood in the last three years. Nearly instant answer. Want to know how many tickets have been written to trucks violating a particular no-truck zone since the city was founded, organized by year and month, you can get that question answered. Want a copy of all contracts under the city manager's signing limit, by year and by each city manager, that is just a few keystrokes away.
Agentic AI is even more powerful which is why it terrifies entrenched bureaucrats. Should we be running audits? Certainly. With Agentic AI this wouldn't be an annual event, not quarterly or even monthly, it would be continuous. It could be triggered by real-time events, like whenever someone with the city makes a charge on a credit card or P-card. Any inflow or outflow of money could painlessly trigger an audit and an audit report. Or, it could be done on demand, on request. Even by one of the We The People. Or, suppose you need to monitor T&Cs for bought in services, so you don't get surprised by vendors like, say, Flock. Agentic AI can do that. Is it worthwhile to monitor processes, say applying for a business license, to ensure proper, timely operation? That can be cone.
Could this happen at the City of Dunwoody? This is what a technologist would say is "possible, but not probable," while a cynic might say "humanly possible, but not with the humans we have available." Don't hold your breath.
