I disagree this should have been flagged. The authors do claim the tasks are "general" but they do have a lot in common with each other, including not-so-far-away misuse... which also happened with AlphaDogfight... and that was transferring from playing Go to flying jets. This is clearly not as big of a leap as the author points out.

Aka - notice that none of the agents in this example are folding proteins. They're all engaged in inherently combat-relevant skills. :)
