I've invented plenty of stuff that 100's of millions of people use every day. Whether I get credit or not doesn't really matter to me. It paid for more than half my life (and those of a lot of people around me) and it made the world a little bit better (and sometimes a little bit worse).

Inventions are a dime a dozen, if you care that much about the credit or the money then you should go try to patent your invention, and if you don't then that's fine too but there is no such thing as CC-BY for inventions (though, technically you could patent something and then put the patent in the public domain 'Manfred' style).
