Thinking about retrocausality again.

Thinking about retrocausality again.
The excellent Emily Adlam on retrocausality in QM.
“It’s troubling to think that the deep structure of quantum mechanics violates such a foundational principle of relativity,” argues Emily Adlam. | https://buff.ly/3ZLehV5
How can we solve this? Adlam argues that the idea the future can affect the past is the key to this quantum enigma.

I've been pointing out that Yud treats "intelligence" like magic for over a decade, completely ignoring complexity classes etc.
One can retort that this was an offhand email when the man was 20, long before I enunciated such critiques, but Yud believes in retrocausality as a central tenant so....

Anyway, now that we have two sets of aspiring overlords instead of just the pre-existing fash problem...
This is what Eliezer Yudkowsky actually believes

so . . . about retrocausality 🧵
I've been reading about this for some time and bring it up partly because one of my WIPs uses this concept. Retrocausality is the idea that future events can influence past events. The mechanism for this isn't known but there's evidence of it happening.

As someone supplied yesterday, there are other ways the principle of retrocausality can be observed, such as with light:

suppose retrocausality exists as just a normal part of physics (assume some kind of eternalism), but then entropy means we evolved to observe only causal interactions. doesn't this imply you could find some way to do deep learning on retrocausality?

Confirmation bias is great because superstition is the archetype of retrocausality

It was fun talking to @davidedmonds100.bsky.social about this, and to combine pragmatism and retrocausality – such a good mix!

In my case rn the big thing is retrocausality. My current understanding is that there's real evidence of retrocausality occurring, but it's not like some big lodestone idea in the sciences. Not like gravity, which arguably gets played around with a lot more in SFF stuff

Just sitting here and my brain is like “what if mothman was a big retrocausality and only happened because we’ve all been discussing it so much in the last several years” lolllllll
