We know next to nothing of what we're going to know in 20 or 50 years.
Sentiment: NEGATIVE
Far more crucial than what we know or do not know is what we do not want to know.
We know a lot of things, but what we don't know is a lot more.
Since we cannot know all that there is to be known about anything, we ought to know a little about everything.
We may not know the whole story in our lifetime.
We do not know enough about how the present will lead into the future.
Nobody knows the future with certainty. We can, however, identify ongoing patterns of change.
Where is all the knowledge we lost with information?
The remarkable position in which we find ourselves is that we don't actually know what we actually know.
We know not of the future and cannot plan for it much.
Nothing is so firmly believed as what we least know.
