2026 update:
The Blue Tribe has remained roughly as extreme as in 2020, but the specific ideology has changed. Now, it’s all about Palestine.
The Red Tribe has continued along the same path as between 2017 and 2020.
The Grey Tribe has come into full fruition, and has spread out if not entirely split, mimicking the wider Blue-Grey-Red split within itself.
Some Greys are YIMBY abundance liberals, merging with the Purples.
Other Greys (who I think of as the core Greys) are the direct outgroup of the Blues. NFTs in 2020-21, AI from 2022-25 and prediction markets in 2026 have all been opposed by the Blues, and are closely correlated because they’re all Grey Tribe.
And finally, there’s the Greys that have allied with the Reds. Musk and Yarvin come to mind here.
I don’t actually know what happened to the Pinks.
What’s going on with interpretability these days?
I found the whole monosemantic sparse autoencoder idea interesting, but this was 2023 and it’s now 2026.
