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.
