Ironic. Every time a company measures its employee output with number of lines of code or commits, devs are the first to point out that management is dumb for using a surface-level metric. But you're doing the same thing here, except with execs and powerpoint.

Powerpoints are just the final output you see. The real work execs do is in the decisions that went into the powerpoint.

No sane board will give decision-making power to an AI they can't blame. Besides, there are probably 100 devs for every exec, so it makes no financial sense to automate execs.
