I won on a large map with 2 normal/ 3 intelligent as the technologists. I used my picks on an additional +50% tech and +1 ship speed. It was a killer combo; in no time I was leaps and bounds ahead of everyone else in tech. And with good enough tech, you're leaps and bounds above everyone else in all the other categories.
The beginning was a little tricky since the smarter AIs wouldn't pay out much for my tech, but after that things took off. I don't know about using the technologists without the extra bonuses from picks, though.
Oh yeah, and don't forget the +1 sensor range. Not huge, but it is kinda useful.
