First the good:
Along with automation, customisation of content will continue to be refined and personalised. This is best illustrated by the Orwellian future vision in the Epic 2014 video clip:

Maybe the biggest gold rush for the next 100 years is the integration of the Web with the human mind. Sony has already taken out a patent on a game system that beams data directly into the mind without implants. It uses a pulsed ultrasonic signal that induces sensory experiences such as smells, sounds and images according to a CNN article from July 2006.Tim Berners-Lee, the inventor of the Web has dedicated the rest of his life to the development of the Semantic Web also known as Web 3.0. The Semantic Web is an evolving extension of the World Wide Web in which web content can be expressed not only in natural language, but also in a format that can be read and used by software agents, thus permitting them to find, share and integrate information more easily. It derives from W3C director Sir Tim Berners-Lee’s vision of the Web as a universal medium for data, information, and knowledge exchange.

Each and every device in a typical household will be able to access this new Web 3.0 through the interoperability that will be built into the software and the hardware.

The Bad:
The arrival of Web 2.0 has seen an unprecedented increase in people giving up personal privacy. This will only continue with Web 3.0 because as your household appliances or computers learn your every mood, behaviour, desires and needs it has to interact with the global Internet, and you are willingly giving away personal privacy.
