Please clarify this claim, since there's an enormous difference between recruitment and outreach, between 2x and 100x growth, between the next year and the next 10 years, etc.
I'd say that trying to do public outreach campaigns with the aim of growing the total number of self-identified EAs 10x in the next year would be a bad idea, diluting the community and lowering its standards.
On the other hand, I'd say that targeting various classes of potentially high-impact EAs is a really good and important thing to do, and that if the movement is doing well it will attend to attract friends of current members, and that because of this I do expect the community to grow several times over again in the next few years if we're doing well.
