will computing move beyond silicon

I think there's a lot of breaks that can happen within silicon. There are a lot of optical solutions out there that are very high-performance. All of the stuff that is used for long distance communication, they are very high-performance. But they are very expensive, so what we're trying to do in silicon is match the performance -- but at a fraction of the cost.
So I think there are a lot of breakthroughs that can happen in silicon, and I think that started 30-something years ago with people realizing that silicon would be a very good material for optical communication.
