Producing text more cheaply is a poor metric for technological advancement. Going to the basics of say energy production, heat engines are already close to theoretical limitations. We already have 60+% efficient power plant so nothing can double future efficiency, and even in theory hitting 100% is never going to happen. The world has better technology and more infrastructure than 10 years ago, but it’s almost entirely evolutionary not revolutionary. Even the tantalizing self driving cars in the near future come with a massive downside of congestion from cars driving without people in them.

As to nanotechnology, we already design molecules to interface with biology via synthetic drugs, so essentially biological nanotechnology is going to be about creating larger structures not smaller ones.
