I see your point but I would say that computers are an extension of human skills.
The computer replaces the canvas and the blank piece of paper but the artist still needs to write and draw upon these medium and create something new.
The skill factor is still there.
I have a much greater advantage as a contemporary solo music artist because I can sing, play pianos, organs and many stringed instruments. Today's musicians and artists need to not only know their instruments and tools but they need to also know the programs and hardware that make art in technology. So one has to have at least two majors, the skill and the tech. One needs to be both a painter/illustrator and a computer graphic designer in order to succeed. One can add many more hats to that also.
Today's artist has to be everything. They have to write the words, compose the music, sing the vocals, play the instruments, record it all, mix, master, create the album art and any subsequent music videos translate that into several audio/video formats, and then publish them to the world while maintaining an active social network with many thousands of people.
People will hear on the radio and say, "That is the London Philharmonic Orchestra!", then they may change the station and hear a techno song.
No, those are "recordings" of orchestras and bands not the actual bands. That is a digital recording of Celine Dion, not actually her. The technology it took to create those recordings is a whole other discipline that a creative content artist is at a disadvantage if they do not include it in their overall art curriculum.
It is like being a great writer and not having a language with which to express ideas.
In today's digital domain, art without technology is dead. One single digital photo can be sent to billions of people within a few seconds. Without digital exposure an artist cannot replicate and mass distribute media... So if technology does detract from art it certainly makes up for it.
As for people who make art without skill. It shows because their music is repetitious and simplistic. So in order to fix this they need to learn another skill and that is called, "production or being a producer". (another hat)
So by carefully evolving digital art over a long period of time complexity can be built in with editing skills.
What I say to "the purest" is they need to get their hands dirty in technology, buy a powerful PC and invest in the most useful art editing software, develop a social following, (there is nothing like winning an important contest and not having anyone to tell...) and don't expect others to do it for you. You may have a long wait before they realize how great you are.
