"Most expected value is in the far future." Because there are so many potential future lives, the value of the far future dominates the value of any near-term considerations.
Why this needs to be retired: just because a cause has high importance doesn't mean it has high tractability and low crowdedness. It could (and hopefully will soon) be the case that the best interventions for improving the far future are fully funded, and the next best intervention is highly intractable. Moreover, for optimally allocating the EA budget, we care about the expected value of the marginal action, and not average expected value.
"What matters most about our actions is their very long term effects."
Why this needs to be retired: there are only a small number of actions where we have a hope of reasonably estimating long-term effects, namely, actions affecting lock-in events like extinction or misaligned AGI spreading throughout the universe. For all other actions, estimating long-term effects is nearly impossible. Hence, this is not a practical rule to follow.
I'm unsure if I agree or not. I think this could benefit from a bit of clarification on the "why this needs to be retired" parts.
For the first slogan, it seems like you're saying that this is not a complete argument for longtermism - just because the future is big doesn't mean its tractable, or neglected, or valuable at the margin. I agree that it's not a complete argument, and if I saw someone framing it that way I would object. But I don't think that means we need to retire the phrase unless we see it being constantly used as a strawman or something? It's not complete, but it's a quick way to summarize a big part of the argument.
For the second one, it sounds like you're saying this is misleading - it doesn't accurately represent the work being done, which is mostly on lock-in events, not affecting the long-term future. This is true, but it takes only one extra sentence to say "but this is hard so in practice we focus on lock-in". It's a quick way to summarize the philosophical motivations, but does seem pretty detached from practice.
I think my takeaway from thinking thru this comment is this:
I do often see it used as an argument for longtermism, without reference to tractability.
So: "What matters most about our actions is their very long term effects, but this is hard so in practice we focus on lock-in".
