Now you've hit upon what I dislike about some of these techniques. As
interesting and impressive as some of them are they lack a certain
potency. If they reliably achieve their goal they are slow; if they have
better throughput then reliability becomes an issue. That is an
oversimplification, of course.

Fantastic clip. Anyone, at the end of watching it, should ask themselves
"What am *I* going to do about it, personally, now, today?"

This is a call to folks who might be waffling: violate that NDA, release
secret information, backdoor your code, pirate out valuable software and
licenses. Find a way to put it on the net, and do it.
