Science, and the confusing of unknowable value with no value

Kevin Ashton, on Medium:

Science begets technology, which begets goods, which beget value. Science is the principal source of value in modern economies. Second, because economies are chaotic, most of the consequences of any particular technology are unpredictable. An example: The watermill led to the automatic loom, which led to general literacy.

Add in the fact that the point of basic science is to know what’s unknown, and we see that the dumbest question requests the unknowable value of the unknowable consequences of an unknown thing. Note that only two of these are “unknowable.” The third, the “thing,” is only “unknown.” And the unknown, not the unknowable, is what should guide basic science.

When the only things you have are beans, the only thing you can do is count them.
