'Maker', to me, means the culture that started with O'Reilly's Make magazine, Maker Faires, and the subsequent culture that grew around it, which concentrated mainly on making physical things, rather than software.

Probably I'm in a bubble where "maker" has a slightly different meaning :/

And what about those who are making tutorials, graphics and digital art, or music? Now I'm starting to worry that there is another name for this group of people as well :D

I agree that the real meaning of the word "hacker" has almost nothing to do with independent software or digital product development, but my experience is that many people started to use it to identify those who are using their knowledge to "hack" together digital stuff. Not to mention hackathons where everyone is a "hacker".

Probably there should be more series like Mr. Robot so people would get a better picture of what real hackers are doing :D
