When you note the massive digitization of technology. you can also note that a lot of math (called "continuous functions") was designed to overcome limitations of digital computation.

This minor intellectual notion COULD reduce the massive disadvantage faced by USA youth (and adults) who could never grapple with math beyond the eighth grade. Maybe their lack of "math" skills doesn't doom them to future serfdom.

But they still suffer "innumeracy." Tragic!! No excuse!! Not even the Asian 15-point IQ edge!

When did "obsolete" become a verb?

If you search for "obsolete" online, you will find that some creditable dictionaries define it as both an adjective and a verb while others only define it only as an adjective.
