This arrests EAs/longtermists from drawing on centuries of knowledge & movement-building
The track record of anticapitalist advocacy seems quite poor. See this free book: Socialism: The failed idea that never dies
If you’re doing anticapitalist advocacy for EA reasons, I think you need a really clear understanding of why such advocacy has caused so much misery in the past, and how your advocacy will avoid those traps.
I’d say what’s needed is not anticapitalist advocacy, so much as small-scale prototyping of alternative economic systems that have strong theoretical arguments for how they will align incentives better, and scale way past Dunbar’s number.
You don’t need a full replacement for capitalism to test ideas and see results. For example, central planning often fails due to corruption. A well-designed alternative system will probably need a solution for corruption. And such a solution could be usefully applied to an ordinary capitalist democracy.
I concede that AI companies are behaving in a harmful way, but I doubt that anticapitalist advocacy is a particularly tractable way to address that, at least in the short term.
As an American, I think this is actually a really good point. The only reason to even consider racing with China to build AI is if we believe the outcome is better if America “wins”. Seems worth keeping an eye on the political situation in the US, e.g. for stuff like PEPFAR cancellation, to check if the US “winning” is actually better from a humanitarian perspective. Hopefully lab leaders are smart enough to realize this.
