Why even TODAY are there NO female inventors :3?

I wouldn't say there aren't any at all, but more males happen to be inventors because more males happen to be smarter than females.

There are and have been. The actress Hedy Lamarr has some significant patents and was elected to the National Inventor's Hall of Fame, for example.

I get a feeling your incredibly sexist by nature..

Seems like mostly men in those fields although that doesn't mean women aren't. Apparently the creator of computer music programming was a female, she made this thing called the bloop and it's really smart when you see how it works.

There are not into it. They have better things to do.
