It's not all being "driven" per se from within the tech industry. For example, John Deere is making huge advances in agricultural equipment that's going somewhat unnoticed in Silicon Valley -- but these are combines that can leave a 3-inch overlap between passes rather than a 18-inch overlap, because they are GPS-guided, for example... this is adoption of technology, but it's being driven by John Deere, and will show up as growth in the industrial equipment sector, not the high-tech sector.
