Bombing that building was an accident due to it being on what was part of a military target and I'm not sure if it was ever made clear whether the building was technically dual use despite also being used as a school. Either way, bombing a bunch of school girls wasn't intentional and nobody reasonable would assume it was.
There was a time we bombed a bus or van with kids in it, but we admitted it and apologized for the mistake. Nobody wants to be bombing kids, first because they're innocent, but second because there is no military advantage to it since it's bad PR.
Many of these targets were identified before Anthropic or OpenAI even existed.
If it wasn't intentional and accident, did anyone apologize for that mistake?
Also the point is, you (Dario) can't claim morality, when he is fine doing business with entities literally bombing and killing human beings in other countries.
You are either fine with it and continue working - which Dario is doing
Or you say, I will not work with you.
For Dario, main thing is money, everything else in his article is bs
