[Altered Carbon] How is Kovacs’s envoy training still applicable in the world 250 years later? At that point tech would have advanced so much it’d be impossible for him to have previous knowledge of it’s workings.

This is a good question.  It seems like technological advancement has plateaued, at least judging by how familiar many things are to him.  This could be explained by how humanity seems to have taken some of its greatest advances from a forerunner race without fully understanding the technology.  As such, humanity may have reached a cap on how far it can advance, at least for the time being.  Heck, (guessing as someone who's partway through the storyline) maybe the Meths are actively repressing change so as to maintain their power.

There's also the fact that his envoy training is good for precisely what he's doing: entering a foreign society and adapting to it quickly.  He may be easily taking in stride what is new to him rather than being a fish out of water, like Philip J. Fry.
