Rob,

Over fifty years later...

I still can't tell you precisely what the message is in STAIRWAY TO HEAVEN. I'm not sure that there was ever a truly cohesive and self-evident message to the lyrics. To bad LZ could not have posted the lyrics here for feedback in the 1960s. The song would be so much better than as it stands.

To some extent myself and others on these song forums can recite basic do(s) and don't(s) of grammar, literature and songwriting.

But mostly, what we can tell you is how we would have written your song in accordance with our own sensibilities.
Every so often, someone comments on something that truly makes me stop and think or brings forward some beneficial knowledge such as you did regarding AI.
