ability to destroy a planet [or digitally clone a voice] is insignificant next to the Force
The ability to digitally clone a voice is also somewhat insignificant next to the ability to destroy a planet. And if the Force was more powerful than the Death Star, why did they bother building it when Vader could just have blown everything up with his Jedi skills?
Anyway, they should open source this, then everybody could be Darth Vader all the time on their phone calls. Although the telcos might get a lot more complaints about heavy breathers.
