Although it can take away from creativity but this can help people learn guitar and open them up to new way of thinking creatively. Its easy to say technology is bad for music when you can already play basically any instrument. Not everyone can afford lessons or find someone to teach them to play. This helps those people.
this is stupid almost like cheating learn on your own is the best way how do you think the Beatles made there music? There was no one back then to give lesson for guitars
