We have a tool in place to develop the product of the future. It could enable us, in the very far future, to be able to build computer devices on an atomic scale.

We will then need alternative structures, and perhaps altogether different ways of computing. Techniques like this can help us gain the knowledge needed to create those alternatives.

We have developed a window into the atomic heart of magnetism. We can now position atoms and then measure and control their magnetic interactions within precisely designed structures.

People want to spend more but this may not continue into the future. For one thing incomes aren't rising and employment isn't increasing. That's why we think there will only be moderate growth in the months ahead.

We know about cases in the US where citizens have looked at the register, taken a gun and shot the person on the list. I don't want that to happen in Germany.

In a case like this there are always calls for us to introduce something new, and people say everything we had up to this point is insufficient.
