Jamie Joyce is a Berkeley-based technologist and researcher challenging incumbent Lateefah Simon.

  • Says she respects Rep. Simon's civil-rights and oversight work but believes the moment requires affirmative AI legislation and aggressive executive-branch oversight rather than incremental progress.[4]
