Shareholders who delegate spending decisions to their proxy who delegate spending decisions to the c-suite, who delegate spending decisions to the managers, who delegate spending decisions to individuals, who can and do delegate spending decisions to automated systems when it is in the interest of the shareholders.

I don't have free access to all of the capital in my employer's control, nor does anyone in the entire org. But I do have the ability to, for example, decide to turn on auto-scaling on the apps I'm in charge of without having to hold a shareholder vote about the issue.
