Reminds me of that story about the casting of Patrick Stewart as Picard. Apparently Roddenberry originally had in mind a youthful, virogous figure much like William Shatner was for Kirk. So Stewart auditioned in a toupee to compensate for his baldness. An impressed Roddenberry realised that the toupee was pointless. Later when a reporter asked him why baldness hadn't been cured by the 24th Century, he said that society would be so advanced that no one would care anymore.

We need to be extremely careful with what we consider “errors”. We’ve been through this before and it never ends well.
