I can't believe no-one's talking about this here. Bill Gates has predicted that many workers will be replaced by software and robots over the next few decades.
This could be the beginning of a new age in which all the labour needed to run civilisation is done by machines and the government provides us all with a basic income leaving us free to pursue our interests like in Star Trek or something. Or it could lead to a new era of mass unemployment and people struggling to survive. Let's hope politicians make the right decisions and adapt our economy before too many people suffer.
