Considering how hard it is for a team of people to simply integrate two different systems I find it laughable that anyone would worry about AI hacking the planet and manipulating everything. And if an automated computer system made a major error and stole a bunch of money we would just turn it off and unwind it all by hand and on paper. I have been doing software for so long and the more experience I get the less likely I see something like this happening. I’m just not seeing any reasonable risk or vulnerability at all.
