Maybe at small startups they are more involved, but the larger the company, the less I think that CEOs or other C-Suite types actually do.
While I also think ChatGPT is over-hyped and largeley incorrect in what it says, I would answer your question with a "yes". ChatGPT is perfectly capable of writing/delivering speeches at MS Build or whatever.
Rather, you just don't understand what CEOs in large public companies actually do. You're comparing them to earlier stage CEOs, who can be more hands on.
When running a public company of a quarter million people, the CEO's responsibility starts to look more like an asset manager responsible for a $4 trillion dollar book.
And no - nobody wants that role replaced by an LLM.
In the long run nobody out performs consistently anyway. We all get hit due to market events.
You may be giving CEOs much more credit than is due. And for all that they actually do, the outperformer is a rarity not the norm.
LLM could certainly fit this. Particularly when trained with all the MBA nonsense education in the world. It wouldn’t be the end of the world and it wouldn’t be substantially better/worse. But it would be cheaper.
The CEO also needs to sell those decisions to the organization to get buy-in on the vision and carry it out. How inspired will the organization be by the direction of an AI? No one in an organization will care about this stuff more than the CEO (if they are decent). An AI can’t care, so why would anyone else?
I say knowingly because actually the sum total of accumulated info for just a month or two of human activity eclipses even today's LLM.
And the CEO decisions are frequently flawed because there's a strong filter of the information from below.
Perhaps a crowd sourced (employee sourced) decision making process would be best with the wisdom of crowds.
Is that actually negatively impacting Amazon's bottom line? One tends to assume they'd do something about it if they viewed it as a serious threat to revenue
Capitalist enterprises (with owners vs non-owner workers) are fundamentally non-meritocratic and exploitative. Everyone works to generate value, and only a small class of workers captures the bulk of the value.
Everything else is delegated to lower level executives and staff.
What, specifically do you think they do?
