It’s not so much a point we can’t see beyond, there is much about the future that is uncertain. A singularity would be a point beyond which you could not see, even if it’s fully explained to you.

For example, you could take a hunter-gatherer from Java, give him an education and he could function in our society. You could not take a homo erectus man and do the same thing.

The future singularity will be a world which you can’t understand, no matter how hard you try, no matter how much information you are given. This has not happened since the adoption of language, I think.
