High variance
I think this might actually be a good idea?!
Shows willingness to give a loud signal to critics, but with gentle push back. Would encourage Gebru to actually read up on what EA *actually is* (she would do that, right?).
It would also satisfy my sadistic impulses towards Rob ;-)
If she refuses, make it known that she did, but in a mentioning way (accusing would be too obvious), which is almost as good as having her on. ("The critics won't talk to them directly!")
High variance
Possible downside: she goes full r-word-mode and produces much more bullshit than can be answered, and makes the convo really adversarial. I doubt this would happen, though, a 2h podcast is not a talkshow, and Rob is really good at keeping things civil.
