As the industrial age is drawing to a close, I think that we're witnessing the dawn of the era of biological design. DNA, as digitised information, is accumulating in computer databases. Thanks to genetic engineering, and now the field of synthetic biology, we can manipulate DNA to an unprecedented extent, just as we can edit software in a computer. We can also transmit it as an electromagnetic wave at or near the speed of light and, via a "biological teleporter", use it to recreate proteins, viruses and living cells at another location, changing forever how we view life.

So you view DNA as the software of life?

All the information needed to make a living, self-replicating cell is locked up within the spirals of DNA's double helix. As we read and interpret that software of life, we should be able to completely understand how cells work, then change and improve them by writing new cellular software. The software defines the manufacture of proteins that can be viewed as its hardware, the robots and chemical machines that run a cell. The software is vital because the cell's hardware wears out. Cells will die in minutes to days if they lack their genetic-information system. They will not evolve, they will not replicate, and they will not live.
