Plausibly, such “ems” may long remain more cost-effective than AIs on many important tasks.
“Plausibly” (i.e. ‘maybe’) is not enough here to make the fear irrational (“Many of these AI fears are driven by the expectation that AIs would be cheaper, more productive, and/or more intelligent than humans.”)
In other words, while it’s reasonable to say “maybe the fears will all be for nothing”, that doesn’t mean it’s not reasonable to be fearful and concerned due to the stakes involved and the nontrivial chance that things do go extremely badly.
