Earlier quoted context omitted.
A surprisingly large number of musicians do use things like written music (a medieval invention, but came into its own in the renaissance) or amplifiers (a modern one).

but you're right that "I firmly believe that AI will not replace developers, but a developer using AI will replace a developer who does not." could have multiple other readings too.
