Why would a Texas Instrument be so powerful and handling everthing. I had to swtich calculators to find out. They can figue out anything. Even how to forget the very idea to put hope in the most obvious things. Thiers is always another way to look at the situation. Food shortages around the world cant be solved by being wayward with one another. One can only go so far. You could design the most brilliant machines to understand what is going on with the world today and you would never find you. It must be as secure as you can make it if you are going to decide what is to be done. Till then. I cant find a mistake in it. Not one.
