There's one other thing about Data that I've always wondered about. In the TNG beginnings, I recall how much of a technological wonder Data was. I would hear things like only the most brilliant of the most brilliant could create an android like Data, and how the technology was so unbelievably superior to anything Starfleet could ever dream of. But as the series progressed and in to movies, it seems as though Starfleet pretty much had it all figured out. I mean they made many repairs to Data, hell, Data himself even created another android Lal, even though she "died" in the end. She was based off of Data's own programming and technology. With all of that said, shouldn't there be hundreds if not thousands of Soong type, or close to it, androids out there presumably created by Starfleet??
