That's an odd thing to be certain about. What is money these days? Data. Not crocks of gold or hoards of silver or stacks of cash... data. Ones and zeros. Computer programs are damned good at data... and money. I have little doubt that there are bank/investment/whatever accounts out there that are managed by computers with no humans involved. Perhaps humans set them up, then forgot, or died or simply lost control of them. The AI almost certainly do not *care* about money, but if they're programmed to acquire it, they will endeavor to do so.
As for lawsuits: if someone hasn't already done so, someone will soon create a system that scans the news, trawls the net, scans various databases looking for legally actionable stuff. Police departments have AI that watch cameras 24/7 looking for illegal activity; AI will be able to look for things that can get someone sued. Perhaps AI will read every single thing that's published and will look for plagiarism, and will sue because of it. Or AI will simply scroll through all video and photos and Google Maps imagery, looking for businesses that might not be in compliance with the ADA because they have the wrong door knob. Maybe the AI won't have legal standing to do so... but maybe it will, and maybe it'll be able to run a line of bullshit so magnificent that it won't matter. Lots of lawsuits are settled for cash based purely on the threat.
And that's the legal way. Criminality will be *easy* for AI. Attend:
Crimebot5000 watches all of social media. Joe Smith, college student at pricey Ivy league school, posts about his current Spring Break in Mexico. Crimebot5000 scans all the databases, finds out who his family are. Finds rich Granny Smith, lives alone. Finds Joe's phone number, is easily able to spoof that number while simultaneously shutting the actual phone down. Finds TikTok vids of Joe, and learns to imitate his voices. Calls Granny, claims convincingly to be Joe (using extra hints gleaned from social media), says he's in desperate trouble and *please* send ten grand to this venmo or that paypal or buy gift cards or whatever the hell. This sort of thing already works well enough when foreign humans with bad accents call random old people with no knowledge of their offspring and get enough money from them for the scan to be worth doing. When AI can do it with complete believability, it shoulf be quite the moneymaker.
Clearly Crimebot5000 will be run by and for the benefit of human criminal enterprises. But other than setting it up, no human involvement will be needed. Maybe Crimebot5000 has no aspirations to anything more. But *other* AI, somehow cut loose to make their way on their own, may find out about CB5000 and either copy the process or simply appropriate it like the MCP.
Ultimately, AI should be able to simply invent money out of whole cloth. *POOF* there's a billion dollars. If the government can do it, so should an AI. AInflation should be spectacular.
