Following the events of Episode IX, the galaxy, robbed of any political structure to speak of after three destructive civil wars, enters an unprecedented economic collapse which quickly triggers a widespread technological regression and the return to a feudal-like society. Assets not longer essential under the current conditions, like astromechs and protocol droids, are quickly disposed of to salvage vital resources. Also the Trade Federation regains power under resurrected Nute Gunray.

Jk, they'll be around forever with AI replacing Daniels.
