I believe the org is in the process of shortening its name from Singularity Institute for Artificial Intelligence (SIAI) to simply Singularity Institute (SI).
I'm irrationally slightly annoyed to have "wasted" the time it took to train my brain to see "superintelligence" instead of "Singularity Institute" for SI back when it was used that way.
Three new research associates. Link to the announcement.
