Once more an informative review. I guess you're not a collector of Traveller editions, are you?
The things lacking, cybergear, robotics, AI and biotech are indeed the things that came to sf in the eighties, and it sure solidly grounds Traveller as a seventies game. GDW actually tried to changed that in the next edition, The New Era. Those changed never worked very well, for various reasons, alas.
The newest official Traveller products have given machine intelligence and some other modern sf schticks more space, but I think that advanced biotech would change the setting into something with too different a flavour from "golden age" sf, which is the core of the Traveller experience.
