RE: The entire genome of the axolotl (Ambystoma mexicanum) has been sequenced, and might give us details about how it regenerate lost limbs and damaged organs

Exactly, no one can know what type of technology we have at that point. Maybe creating new organs/limbs is not even needed anymore because we've found something better to replace it with? ;) Maybe a bit of a stretch for 50 years though, and time travel probably is as well. But who knows?
