The community has been in a deadlock over making FSRS the default (https://github.com/ankitects/anki/issues/3616), and I wonder if this will lead to some resolution.

It seems like the core things that Anki needs are new user experience improvements, and algorithm updates. SM2 really shows its age as compared to other algorithms.

>>Shank+Ve1
Is there that much of a difference?

https://www.supermemo.com/en/blog/supermemo-is-better-than-f... seems to suggest that yes, it is a major improvement over SM-2, and given how critical they are of FSRS I'm happy to believe them. SM-2 to my understanding is basically the simplest possible spaced repetition algorithm - I think something like 'double the review interval if easy, otherwise multiply by some difficulty factor to reduce this interval depending on which button was clicked'.

That said, even SM-2 is probably vastly superior to just not doing SRS at all.

>>bigDin+kL1
Isn’t the linked article claiming that SM is superior to FSRS?

>>asymme+eM1
SM is claiming that the latest versions of the SM algorithm (namely SM-19) are vastly superior to FSRS (maybe it is?).

They state in contrast:

We do not dismiss the work behind FSRS. It is a commendable open-source effort and a marked improvement over ancient algorithms like SM-2.

For context, Anki uses SM-2's algorithm (albeit apparently heavily modified for various special cases) if FSRS is not enabled.
