I would prefer to have invented a machine that people could use and that would help farmers with their work - for example a lawnmower.
Terrorists also want to use simple and reliable arms.
Man keeps inventing things all the time.
I'm proud of my invention, but I'm sad that it is used by terrorists.
I tried a dozen different modifications that were rejected. But they all served as a path to the final design.
Then it was like a genie out of the bottle and it began to walk all on its own and in directions I did not want.
