That too, but the people in charge of the military are strongly incentivized both to consider the possibility that subordinate machines will try to kill them and to figure out how to not let that happen. I tend to suspect they will figure it out. Companies, however? Markets? They will absolutely start handing over control the millisecond it becomes profitable to do so. No rationalization will be too steep and no political opposition will be too strong when the prospect of rich people getting paid for being rich goes on the table. The people who enable the takeover will make out like bandits and those who oppose will lose everything. Until, of course, the "winners" become unnecessary and are cast aside.
A military-origin takeover requires a human fuckup. Economic/political takeover just requires capitalism.
