Honestly my hope is the AI become in charge of the stock market and accidentally send it into a death spiral because of some type of weird infinite paperclip machine bug
Are they still having humans input the commands after review though? I'm waiting for full on AI automation of stock portfolios and how badly they could react to some type of systemic factor in the market no one planned for (i.e. another crisis of capital).
I'm pretty sure that has already happened. IIRC there was at least one time when trading was halted due to the HFT algorithms going berzerk and costing billions in losses in some sort of spiraling war.
