It's never OK to physically attack someone like this. Full stop. Separately; Sam's belief that "AI has to be democratized; power cannot be too concentrated." rings incredibly hollow. OpenAI has abandoned its open source roots. It is concentrating wealth - and thus power - into fewer hands. Not more.
If we are going to say violence isn’t okay then it is important that we be clear about the boundaries of what we define as violence. Theft is a nice analogy here. The default model of theft is property crime but the largest type of theft is wage theft. If we fret about violence done against individuals but not violence against groups our attention is going to end up steered in a narrow direction.
