Wow, I didn't know the Sim Ray could do that. I've got one in my household inventory from a Scientist many generations back.
I enjoyed the career too, mostly because you don't have to actively play it - I just sent my Sim into the rabbit hole every day, and as long as I made sure she got her breakthroughs, she advanced to the top. (It also has the advantage of a regular schedule, so by the time the kid was done doing her hour on the monkey bars for fun and fitness, the mother was home to help with homework.)
The cloning machine has been useful, and I liked using the worm hole generator to take both my Sims to Sixam to search for collectibles and plants. (Still need the quill fruit - it wasn't in season when they last visited.) I did not manage to get the invitation to the party on Sixam, unfortunately - one of those things I still want to experience in my game. Maybe when my tech guru finishes her career (she's going for that special gaming mat), I'll have her become a scientist.
