A blind person could pretend to be sighted though. There have been blind authors who wrote about sighted characters, for instance. They need not experience the thing themselves. Just learn from experience how sighted people behave and describe things, and mimic that.

Can you provide any examples of blind (from birth) authors giving convincing visual descriptions from the points of view of sighted characters?

That seems hard to believe.

You can explain red by saying it's a "warm" color for example. Metaphors work, analogies, senstion from one sense can be explained using sensations from another. Now you need to have at least one sense, which machines clearly don't.
