@Tobotron,
Positronic brain matrixes operate with tera-byte capacity and even greater, this is in processing speed, not memory, memory would by in a factor of 10 the the 50 power. We are No Where Near that now, perhaps nano tech will expedite the process, but who knows for sure?
and @oratio, light sabers are plenty useful, just use the force…plus the ability to defend oneself from energy weapons is always a plus, not to mention the fact that metal sculptures would be much more efficient.
