For many years, there has been a growing concern about the emergence of a "digital divide" between rich and poor. The idea is that people who don't meet a certain threshold income won't be able to afford the investment in computers and internet connectivity that makes further learning and development possible. They'll become trapped by their circumstances.
Under proprietary commercial operating systems, which impose a kind of plateau on the cost of computer systems, this may well be true. But GNU/Linux, continuously improving hardware, and a community commitment to bringing technology down to cost instead of just up to spec, has led to a new wave of ultra-low-cost computers, starting with the One Laptop Per Child's XO. These free-software-based computers will be the first introduction to computing for millions of new users, and that foretells a much freer future.
