Sounds about right, unfortunately.
I read a bit of the article and watched most of the YouTube video embedded in it. It's definitely worth a read/watch.
The video narrator keeps going back to the argument "they didn't tell the agents to do XYZ!" Yeah no shit, that's the whole point behind agents! They are autonomous and extrapolate actions based on the situation they find themselves in. The implication the guy is trying to make is that these agents are sentient, which is a stretch and a bit misleading.
But... it's still a really interesting series of exercises. Especially the Minecraft one. And if nothing else it gives researchers pointers about how they can improve agent decision-making, and everyone more insight into how they operate.
