Do you have a specific definition of AI Safety in mind? From my (biased) point of view, it looks like large fractions of work that is explicitly branded “AI Safety” is done by people who are at least somewhat adjacent to the EA community. But this becomes a lot less true if you widen the definition to include all work that could be called “AI Safety” (so anything that could conceivably help with avoiding any kind of dangerous malfunction of AI systems, including small scale and easily fixable problems).
