Alan Turing gave us a mathematical model of digital computing that has completely withstood the test of time. He gave us a very, very clear description that was truly prophetic.
Digital organisms, while not necessarily any more alive than a phone book, are strings of code that replicate and evolve over time. Digital codes are strings of binary digits - bits.
If you spend time alone in the wilderness, you get very attuned to living things.
I don't know a single person who is not immersed in the digital universe. Even people who are strongly anti-technology are probably voicing that view on a Web site somewhere. Third-world villagers without electricity have cellphones.
When you click on a link, you are replicating the string of code that it links to. Replication of code sequences isn't life, any more than replication of nucleotide sequences is, but we know that it sometimes leads to life.
