> Actual effective managers do much more

And how many managers are effective vs. only information funnels?

Even “only” information funnels have value if they seek out valuable info, filter, curate. In reality some funnels in this context mutate the message they’re supposed to pass on :-)

Firing a bunch of ineffective managers because they can easily be replaced by AI seems like a net improvement to me.

the key for managers is like business owners

1) understand what success means for their area 2) assemble a team and remove roadblocks for them to achieve 1.

The bad ones tend not to be information funnels.
