This is a useful post, and it's helping me think through my own decisions. Some quibbles:

Most generally, it seems like effective altruist organizations, like all organizations, are constrained by logistics and management and cannot absorb money and talent as quickly as it can be flung at them.

If your talents are logistics and management, this argument leads in the opposite direction!

if you don't fall into the upper limit of talent, it would be more advisable to ignore the haste consideration here and work on cultivating further talent first.

These two paths aren't necessarily exclusive. For example, I've heard people argue that founding a tech startup is both the best way to earn (expected) money and the best way to cultivate talent.

Given these constraints, I think it's worth taking the haste consideration somewhat seriously, but perhaps less seriously than it may seem on face value.

Strong agreement.
