Yes, me too. Kinda creepy huh?

We keep telling 'em "base 10 base 10" but if you ask
"teacher, what's base 10?" they consult Common Core
and draw a blank.

"I dunno Johnny, and who told us to ask such questions?
We know what the principal says about 'questioning
authority' now don't we Johnny? You remember the last
time?"

[ Nurse Ratched imitation ].

You'd think it'd be headline news, this Great Dumbing
Down, but you see how it works: the rule of thumb is
never to write above an 8th grade level, and now that
8th graders have no clue what a "number base" is, you
can't write about it.

As Rumsfeld might put it, they don't know what they
don't know (and we're not about to tell em). Or "you
go with the Army you've got" (whether or not it has
'number sense' I guess is the thinking -- seems risky
for a civilization to really be this dumb, but "ours
is not to reason why...").
