Brian Eno was 100% right about ambient music, but he was just wrong about what form it would take. Basically, his music is so unintrusive to the point of being sleep-inducing for many, thus at least a little more intensity is needed. What really became the ambient music was 24/7 lofi hiphop streams. That kind of music is still very abstracted from a human composer, it just happens to have slightly different sonic qualities and sociocultural context than Eno, so it appeals to a wider audience.
