It's definitely a challenge, but it's even more than that. Beyond the basic need to understand what you're saying, a computer needs to understand what you're trying to do. So humans talking to computers present variable challenges.

You really had to learn to protect yourself from all Gooks in Vietnam, or else you would end up dead.

I had what I would consider a normal upbringing and, which to me, a normal American up - upbringing for an American male child almost gears you towards going into the military.

Perhaps the thing that most got to me was the ide - the whole thing about lying, and how pervasive lying about Vietnam was.

Lieutenants lied to captains, captains lied to colonels, colonels lied to generals, generals lied to politicians, politicians lied to the people. Right on up and down the line. It was like a complete and total, not a total lie, but just like so much, it was like PR, in other words it was like okay, we've got to sell the war to the American people.

The military is sort of the ultimate test of proving that you're a man, and certainly that whole idea was very much uppermost in my mind when I joined the Army.
