This is what Google and Facebook would like us to believe, but I'm not convinced. What it really comes down to is that they'd very much like to stay in the realm of automation, especially Google who are notorious for keeping humans out of the loop at any cost. See the long history of problems with their automated "developer relations" on Android. And the problem is that the disincentives for continuing to fail at these halfway-automated tasks are simply not strong enough to force their hand.
So they can just keep "doing their best" with automation, even though automation itself is far from the best they could do.
