“Once upon a time, there were physical CDs. The order of each song mattered, for the album was often played as an uninterrupted piece. Then came the computer and music became digital. You could play all your songs in the order you wanted and easily create compilations based on your musical taste. Then came the Internet and it all became messy. Streamed, remixed, compiled, Music was everywhere and listeners could seamlessly interact with it.
Once upon a time in a parallel world, there were physical classrooms and teachers. The latter had a standard curriculum to deliver to their classes and students’ interests couldn’t really be integrated. Then came the Internet. Whenever, students could also take classes online, thus joining worldwide cohorts through “Massive Open Online Courses” (MOOCs). Everything became possible.”
