Why do we even have school teachers? Why not just use computer based teaching so you have better QC and give more kids the opportunity to listen to an expert who is also a great communicator? And then a remote teacher to answer questions? It's how you learn systems today at the airlines, no?

It'd be better for a lot of failing schools who probably have failing teachers. I went to a failing school, one of the worst in the state of Virginia. I had failing teachers. Would have loved to have had computer based training. In fact, you may not even have to be in a class with 20-30 others and have the discipline issues of 1 disrupt everyone ability to learn, much less 10, 20 or 25 of them being disruptive.

FWIW, my mother was a public school teacher for 25 years. Her school got to the point it had to refuse to hire teachers from a certain nearby college because they were so bad, and her school was not in a good area to be picky about such things. Yet they refused to hire these teachers, but don't worry, these teachers were hired at other schools. Like mine.

So... what's the question again? Oh right, why should an aluminum missile with sometimes four hundred people in it have humans controlling it 14-20 hours a day?
